Hey Guys,
I have a question i keep getting this error on my phone
Code:
sim card not recognized ,please insert sim card
while the sim card is inside just received it from the US/Verizon about to use it for IAM GSM Morocco , i know verizon use CDMA and also know that the phone is unlocked but i can't seem to get my sim cards recognized i tried 2 micro sim from IAM, and the option to check GSM instead of global or CMDA i cant i get blocked by the same error i rebooted the phone no changes
Ok when I got my Droid M I got the exact same message. I assume you're on the stock rom. Even though I got this message, I still managed to get access to my local Network because the Droid M does not disable GSM if youre outside the U.S.A.
You're in Morocco so you shouldn't have any problems getting GSM network to work. Try another sim. The message you are getting is easily disabled using Titanium Backup. I'll post it up once I find it, I haven't had to do it for a long time.
Sent from my XT907 using XDA Premium 4 mobile app
Thank you for the quick response Yes i did manage to bypass the activation screen just so i can use the other options but in the beginning it didnt even let me go farther than that message I when i bypassed it i went to select GSM it didnt let me the sim cards work on other phones
I did try another sim card that works in another phone i get the same error i cant even select GSM in the setting its always in Global
HTC Desire 816v is a CDMA + GSM dual sim phone where the first sim (CDMA) is locked. I was able to unlock the first sim as follows:
1. Rooting the device by following instructions (1 to 4) in http://forum.xda-developers.com/showthread.php?t=2775801.
2. Adding the property specified in http://forum.xda-developers.com/showpost.php?p=44255011&postcount=10.

Thanks for the info. I have the single sim version with Sprint's lovely locked down features. However, it is GSM capable. I've gotten it to access GSM capability with a different carrier sim, but I'm still stuck S-ON and invalid sim. I'll try just about anything to fix this issue.

i follow those steps too, i first ulock my htc bootloader, then rooted, then unlocked sim through adb shell. However, when ever i put a different sim i never got any signal just a message "Invalid UICC something something" I even purchase an unlocked code but this phone wont ask for unlock code. I would give anything to unlock this too and use in tmobile prepaid with their refarms 1900mhz, i could get 4g if i could make it accept sim. I have virgin mobile too. So can you make calls or tx with the your sim card from another carrier? did you change anything else?

I am able to add different carriers and make calls, use data, etc. Do a getprop and verify if the propery is indeed set after the reboot. Let me know what you find.

After a reboot, do a getprop persist.radio.simlock.enable and paste what you get.

I would chime in here, but I got carried away with my project. I had the gsm active, then I got the invalid sim message to go away. The sim in my phone isn't active with my live service. I have the service active on my old-old phone that doesn't have a nano sim and haven't switched it over. I was just testing the capabilities.
However, I had a WiFi problem that came up with a ROM change. Essentially, I should have addressed the problem before proceeding with anything else. I am in the middle of cleaning up my mess. I just don't want to share any invalid information. I'd rather ensure that I have a clean device and process. :fingers-crossed:
Note: I will mention that I did use the process to unlock more bands in a Qualcomm device using QPST tools.

Hi, Did you manage to get the "Invalid UICC" message to go away? I followed the same steps with a HTC Desire 816 Virgin mobile variant (unlocked the bootloader, rooted and changed the property through adb shell) and I still can't get the phone to work with a GSM sim. I purchased a unlock code as well but can't find any prompt where I can enter the code.
Thanks !

I followed these steps with a Virgin Mobile HTC Desire 816. But I can't get the phone to work with a GSM sim When I enter the SIM I get the message "Invalid SIM Card: 4G services are unavailable as the SIM/UICC is invalid"
Is there any way I can get this error to go away and unlock the phone?
Note:
Phone is still with S-On
In my country only GSM carriers are available.
Many Thanks!
Disable UICC
I dont have an HTC 816 anymore yeah got impatient and just bought a optimus g pro and sold the HTC desire 816. However, i became more knowleadge ever since. For those who already unlocked their HTC Bootloader and Have rooted their cellphone but are getting the "invalid UICC" message please try this.
Download any Build prop editor from the play store. Look for the settings on "UICC.Mobile_equipment.config". Open it and you should see 1 or 2 fields, "property value" and "default values" write the numbers down or take a picture so that you can revert this process in case necessary. This where virging mobile lock the cellphone to the sim/UICC thats in your cellphone. change those to 0 and restart your cellphone. im pretty sure the phone should not give you that message and should accept the sim card you enter or ask you for an unlocked code.
In the worst, it will fail and you would just have to re enter the original property values. I notice all my other cellphones have these property values to 0 ( which means disable or none set) but all of virgins have somthings else
Try and let me know how this works for you.

hi. i do also have the virgin mobile version of the 816. i downloaded the build prop editor and went in. but the i cant seems to find UICC.Mobile_equipment.config. any help
sorry i dont own an htc desire 816 any more. However, this is where you would disable that stupid UICC security but Virgin Mobile are jerks like that and probably remove that option. Was worth taking a shot to see if it was there since all other android cellphones with sim cards have that option. Virgin Mobile will start unlockin some cellphone's starting February 2015. So were not that far from that date. Lets wait and see.
Thank for info

The radio frequency thing had already screwed my first sim network. I accidently clicked on USA band & from then, my 1 sim slot is not detecting network & there is no option to revert back the frequency.
Can't flash radio also as we are S-ON.
@jithumon..
I cant really help you much because this thread is focused on Virgin Mobile 816 with one sim slot only.
Have you tried changing the preference setting to gsm only then change the frequencies.. I have the American version 816 desire which is a bit different from yours . And yes once we figure out how to get S-off will be golden. :good:

Progress on Desire 816 Unlocking?
Any progress on unlocking the Desire 816 to use on GSM?
I've seen varying info on the bands available, is there any chance it will work on T-Mobile, on LTE?
This would be a great phone to use on GSM, as it costs less than $200 new, which is great for a phone with a large screen, stereo speakers, and two high megapixel cameras.

I would like to know too; but since the SIM slot in the vm version is only for lte, it could be tricky. If you remove the SIM, the phone still works fine, but no 4g/lte. CDMA is tricky...

Hi Guys,
I am writing this Thread believing that I will get a solution as Yota company has not provided any solution after 15 days trouble shooting. I just brought the phone from Russian seller through eBay.com to India and after 2 months of fight from the local customs office I just got my phone. I was very happy and was floating in air to have the first dual screen phone in my hand. The phone was flawless with dual screen was working awesome. The phone came with lollipop update. I switched on the phone with out inserting the simcard, the phone prompted for a small 350 MB update and I just update the phone. Then I just inserted the Simcard after which i started facing issue. The issue was the phone is able to read and shoe the service provider name but there was no network signal and it was showing only emergency calls. When i tried to make calls it showed network no registered. I tried with different simcard which resulted in the same issue. I though it might be a simcard issue and checked with my old phone but there was no simcard issue. So i just contacted the Yota tech team through mail to help me on this issue. They asked me do some basic troubleshooting but there was no use after 15 days they asked me to ship the phone to nearest service center which is in Russia. The issue is to and back from Russia customs will cost me the price of 2 Yotaphone fist generation phone price. So I through of resolving this issue myself and researched in online. I found that Samsung phones were also facing the same issue after update and tried all the solutions given in internet but there was no use. Finally there was a solution asking to root the phone and install the ariza patch which would solve the issue. I just rooted my phone and when I installed the ariza it showed it was not compilable for yotaphone 2. I just searched in XDA forums and could not find anyone reporting the similar issue with a solution. So I through of creating new thread in hope of getting a solution in this issue. Please help me in this issue by creating a patch or any solution which will me help me out of this. I am not able to use the phone as the basic call function is not even working reset the phone is a heaven.:crying::crying::crying:

Do you still have this problem?
I wasn't sure at first, I thought it was my sim card, but I have tried 2 different networks sims and they both get no signal in my Yotaphone 2...
The network's name does appear, so the sim must be being read somewhat, but I always get no signal.
I literally have no idea what to do.
I too turned the phone on without a simcard, flashed the RU latest rom, flashed TWRP, rooted it etc, surely that has nothing to do with it...?
@bharath9962 ! I fixed it!
I have no idea why this happened, and I spent a few hours trying to fix it, very angry. I downgraded to 4.4 to see if it would help, put back the native China rom that came with my phone (accidentally deleted my backup too...)
I bought a new sim card just for this phone because the old one did not 'work'.
This is not a popular phone so it's hard to find information, anyway... I'm very relieved now. I can only imagine you gave up...
I found the answer here - thewichitacomputerguy.com/blog/how-i-fixed-your-sim-card-does-not-allow-connection-network-g1
1. Open the phone dialer
2. Enter: *#*#4636#*#* (Once entered, you will be taken directly to a "Testing" page) [4636 spells INFO]
3. Tap Phone Information
4. Scroll to the bottom of the screen and you should see a button that says radio off. Hit this button and when it reads radio on Hit it again to turn the radio back on. <-- (Not a Typo)
I rebooted and waited a few seconds, no signal. I turned on airplane mode, turned it off, and it worked!
Now I can go back to RU 1.99 and reinstall all my stuff...

My country is in Asia but I believe this does not matter - the problem was that somehow the radio (cell phone function) was 'off'/glitched, and had to be turned on+off to make the phone function again. Using a different country's sim card would not fix this problem.
As I wrote above, we both share the fact that we first turned our phones on with no sim, and updated. Maybe just a coincidence...
Just try the guide and please let me know if it is fixed!

Hello!
I try to figure out what you did but I get stucked in number 10.
Actually I flashed my Yotaphone with the chinese radio the first time, but I don't get good connectivity.
Anyways I try to do what you wrote, but when I tipe the first line (first fastboot command), cmd keep saying waiting for the device... maybe is that I'm impatient but nothing happens.
I try other USB ports and nothing works...
So actually I don't know if I'm doing it right or if I have to wait for a longer period of time (10 minutes or more).
Any help would much appreciated.
Cheers!
Hi there,
you don't have ADB drivers installed. Google for "universal adb driver" and install. There is driver included with yota 5.0 firmware (C:\Program Files (x86)\yotaphone_flasher\Driver\Google), but any other adb driver should work as well.
And use original yota usb cable!!!
It shouldn't take more that a few seconds for those commands to execute.

Had the same problem
Hi all, I had the same problem when I flashed russian firmware (YD201) over my phone which originally had honkong firmware (YD206).
I can inform that for me it also worked to flash the Chinese firware with yotaflasher.
However, when I tried to only flash the radio, it seemed it did not work. So I flashed the complete chinese kitkat firmware with yotaflasher and then afterward just removed/renamed the radio folder when flashing the newest russian lollipop firmware. Everything working great now, even was able to do some ota's without any problems since the ota's did not update anything of the radio img's.
And indeed you first need to make sure that you have the fastboot drivers installed and your device gets recognized as fastboot device by your PC.
You can test this by doing "fastboot devices". If you device turns up there as a fastboot devices, then the drivers and connection from pc to phone are ok.
Good Luck!
Thank you deepmnd and tomgaga.
Actually I had to activate developer options... And then reinstall the ADB cause, aparently I had it but it didn't work.
After that the instructions worked perfectly, but I still have network issues.
I don't know if it is because I have a MVNO (Mobile virtual network operator) and the phone has to change between the networks ( the one that provides the network and the MVNO).
I think that when it changes from one net to the other is when I lose connectivity and sometimes I have to search the network and choose it manually.
So this problem actually happened to me and the solution was to activate Roaming services (but I dont' know if is actually the same problem).
Anyways I can see that I connect to EDGE, HSPA/HSDPA and LTE.
For sure there is a way to monitor the network and check wich ones works.
Another guess is that being a phone for the chinese market, and the lack of the 900mhz band is causing this ¿?
So at the moment I'm losing signal just by walking on the street and I live in a big city. It seems that LTE and H works fine but I don't have a a way to assure this.
When I will have a spare time I will try to reflash the phone with the instructions deepmnd provided and see if it will work.
Thank you for your help!
Any advice will be appreciated!!
Update:
I try tomgaga approach I will test it just to see if is the network or my provider
Does anybody know which bands different firmwares support?
Reception is incredibly bad in my case (206 flashed with EU firmware).
It'd be nice if somebody has any info on unlocking different bands for yotaphone2.

I have the same problem as you, I will try this weekend to downgrade to the older chinese rom and check if the reception get better.
And if then to the latest RU rom.

Thanks for that, it helps a lot to clear the situation regarding the two models.
Now, taking in account deepmnd´s solution above, would it be possible to find those missing bands from the original 206 which are not available to the updated (and then international, 201-) version and add them individually, file by file via the fastboot flashing?
I followed deepmnd's instructions, and my phone now connects to GSM/EDGE, which was not possible before using the EU Radio (latest EU rom). Thanks for this!
Unfortunately it now preferably (!) connects to EDGE, although the LTE/WCDMA-Option is prioritized. I can force the phone to connect to WCDMA by using the WCDMA-only-option, but in this case it does not commit a fallback to EDGE if 3G is missing and I have no connectivity at all, unless I change the band-options and force a connect to EDGE. I'd like it to switch between the bands automatically, as my YD201 did without problems (in Germany).
Any hints to solve this problem?
Thanks in advance, Knut

Fix for Yotaphone 2 YD206 from China
If you already flashed the phone to latest EU 5.0, you can skip 1-5
1. download via FTP: fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/yotaphone2_flasher.exe and install
2. run flasher and download latest EU rom (2 - 5- 7)
3. turn off the phone and turn it on while holding volume down - this will boot the phone in "downloading..." mode
4. in the flasher press 1 (Flash the cellphone)
5. the phone is now on 5.0.0-EU1.1.124b and 2G is not working at all and 3G is connecting only to 2100 MHz (on my cell network)
6. download via FTP: fw.ydevices.com/YotaPhone2/Firmwares/CN/4.4.3-S01-003-CN1.0.3.32a.zip
7. unzip the file and copy \radio to c:\program files (x86)\yotaphone_flasher
8. run cmd and go to c:\program files (x86)\yotaphone_flasher
9. repeat step 3.
10. run next lines:
fastboot flash modem radio\NON-HLOS.bin
fastboot flash sbl1 radio\sbl1.mbn
fastboot flash rpm radio\rpm.mbn
fastboot flash tz radio\tz.mbn
11. reboot the phone and enjoy 2G and strong 3G signal

Thank you! I had missed calls and did not know what caused them. Then I noticed this happened when I was not on LTE network but on WCDMA or 2G network. And this seems to have solved the issue for me as well.
Hello, hoping someone can help out, I bought a AXON 7 mini hoping to use it in Iraq, but it does not seem to want to register on any network outside the USA. In the USA I was using a Tracfone T-Mobile SIM and the phone worked great. As I traveled across Europe the phone would not connect to any networks (Germany and Turkey), I figured it was just the SIM not allowing roaming. When I got to Iraq I purchased a Korek SIM and still no dice. I phone sees two networks but will not show any service. I have tried SIM cards from other phones with active service and still nothing. I have even tried a SIM card from ASIACELL and still no dice, it sees the providers but will not show service on the network. When I click "automatically select network" the phone response "registered on network" but still no service. I have tried the usual reset all the way down to a factory reset.
MODEL# ZTE B2017G
Android version# 7.1.1
Baseband version TA.2.1.c1-00101-8976_GEN_PACK
Build # ZTE B2017G_USAV1.2.0B14
Thanks for the Help, Jeff
Flashing EU ROM
Could I safely flash the EU Firmware located here, https://forum.xda-developers.com/axon-7-mini/development/firmware-stock-firmware-t3696538 safely to my device. From what I have seen this may fix the problem.
Thanks, Jeff
Fixed, the long way

Phone now seems to be fully functional with aid of a lot of reading an testing. I can also replicate the issue consistently. The original issue seems that the pervious owner, or ZTE set the operating band to "United States." Once this has happened the seems to be locked to USA networks, even though it still sees the other networks. Using *#*#4636#*#* method, you can try to change the band, but only 2 options are there "800 cellular" and "United States," I tried to change to 800 but get the response "unsuccessful." So for the fix!
Thanks to all the hard work here, I was able to install the boot loader unlock update for my phone found here: https://forum.xda-developers.com/axon-7-mini/development/unlock-official-bootloader-unlock-t3690496
I then proceeded to install TWRP, backed up the entire system, and then installed Linage. Then used *#*#4636#*#* and the band now had a third option of "Automatic," selected that and bingo, service in Iraq. Recovered the phone with the backup and the fix stuck. Of point in Lineage there is five options in the band selection, 2 options are duplicates (USA and Auto), I assume for each SIM, and you have to select both autos otherwise only one SIM will work.
This probably could have been fixed with a ROOT application that allows you to enable additional bands, but I was never successful in ROOTing my phone.
Hi guys!
I'm from Venezuela, I recently acquired a Nexus 6p (h1511), so yes, I'm a noob. When the cell phone arrived in Venezuela, I connected it to the Wi-Fi network without placing a SIM card, and there was an update notification, I executed it, anyway it already came with Oreo 8.1, the update was December, the one that had It was November. After updating the SIM of the operator Movistar, recognizes it since it says "Without service - Movistar", when trying to call it shows the error "Mobile network not available", when trying to do a network search, it gives error, sometimes to one side of the signal bar, appears an R (Roaming I guess) ... I've been doing a lot of research, believe me I would not be creating this post if I was not so desperate, I have many doubts
I took it to a technician, he looked at it and said it was CDMA that there was nothing to do, he wanted to sell me a GSM motherboard, I told him I would think about it, it was strange for me to be just CDMA, I investigate more and I realize that it's dual, and it changes from MEID to IMEI when I put the SIM card ... I did a factory reset and it did not work. I used the options in *#*#4636#*#* the default is LTE/CDMA/UMTS Auto (PRL) ... I tried to put GSM Only or Auto or any option that included GSM. Without apparent results, I think that it did not even change the default option, the radio bands are few, all from the USA (logical being the USA version of the cell phone) ...
Investigating further, I understood that the problem persists in Android Oreo ... Under the official firmware of Google 7.1.2, I follow the steps, I do the unlocking bootloader, flash vendor / radio, flashing system, in the end there is an error , something about user, I really do not remember, something like that could not erase the user partition or had no permissions ... The issue is that I turn on the cell phone, start to do an erasure, then start asking for google account, etc. ... I configure it, but I see everything the same, I enter the configuration and details of the team, it keeps dialing android 8.1.0, but I see that the base band has changed, some apps have changed, like the application of calls ...
Does anyone know what happened? (And no, the SIM problem was not fixed) :crying:
I want to install this ROM
https://forum.xda-developers.com/nexus-6p/development/rom-chroma-11-08-2015-lockscreen-navbar-t3244444
According to many sites and here in XDA comment that it solves the problem, but this is 6.0.1 ... It means that I must flash 6.0 stock? To install the custom? Or can I install on 8.1?
Any other more updated custom rom that solves this problem?
Thank you! :fingers-crossed:
