U in Canada with non3G sim?

Here in the US I am using T-Mobile, wich doesn't have 3G yet. So, I probably don't have a 3G sim in my Hermes, and everywhere I go, I always get only a G next to my phone icon. However, when I went to Toronto, Canada, this past week, the G changed to a U. Does that mean:
1) UMTS network was detected, but all it did was detect it, and keep using GSM?
2) UMTS network was detected, and I was able to connect to it, because the 3G in a 3G sim cards is for internet access only,
3) the U is for internet connection availability only, and doesn't affect the cell voice phone part of my TyTN?
or
4) I somehow got a 3G compatible SIM card, and had I wanted to, could've been charged $10 every 8 to 10 seconds for downloading REALLY fast (I get charged $10US a meg if I use web outside of USA)

Hello rassah,
In order to have a 3G service you do NOT have ot have a 3G SIM (also known as USIM). The network is backward compatible and will allow you to use whatever your SIM card (or the network) authorized you.
I am also TMO subscriber and in some countries I could use UMTS and in others only 2.5G (GPRS/EDGE). Technically you have no limitations to do so so its up to the commercial arrangements between TMO USA and the other operators.
So the bottom line:
a. Your device detected UMTS and the network allowed your device to be attached to the 3G network (hence you saw the "U").
b. You probably have a SIM and not USIM (like you mentioned TMO still does not have 3G network ready for commercial use).
c. It is perfectly OK technically to connect to a 3G network even if you have 2.5G SIM card (pending you are authorized by the network to get such a service).
You can do a simple test next time you are in Toronto or other place where you see the "U". Go to www.dslreports.com, they have speed tools, try to perform a speed test and if you are connected with "U" you should get 3G speed results (again, depends on the network and the quality of the signal.. you will see a result of something between 200k to 300k i would guess)
PS: You are right about the cost per meg. But look at the 3G speed as you get what you want but just faster so the bottom line is - you are being charged the same as 2.5G just get work done sooner

Rogers Canada 3G Network help

Just picked up a Hermes 8525 off of ebay.
While upgrading to the latest WM 6.1 roms available - I have been picking up the 3G network in my area here in Montreal.
I do not have a 3G sim card, and do not plan on using any of the data features either. I pretty much just use it as a regular phone - surf via wifi. Am I actually on the 3G network ??
I also do not have a 3G plan with Rogers. Is there any benefit to 3G if just being used as a regular wireless phone ??
If not being used for any data features, etc - will there be an additional charge applied ??
Should I just force the phone to GSM network only - instead of auto ??
Any feedback greatly appreciated
Have a good one

3G is data and voice. So, even if your not using the data plan your voice connection still auto connects to 3G network or Edge.
You wouldnt get charge for data as long as your 3G data connection is disabled.
You could force it to use a specific band (i.e. 850/1900 mhz) but you might have a bad connection on some areas since the phone auto connects to stronger signal. Hence better (sometimes) voice quality.

Mate 8 Internet Issue with T-Mobile

I am really sorry for post duplicated, but I have only 5 days to return this phone which I absolutely love.
However this Internet issue is really bothering me.
I just bought my Mate 8 with build number NXT-L29C636B103, but I have been experiencing mobile data issues with my T-mobile carrier that only when I get 4G symbol, I can go online. Whenever I am getting either 3G or H+, I can not connect to internet at all.
I have tried my wife's T-mobile phone, at the same location, her phone will get 4G LTE, my phone will have 4G, whenever she is getting 4G, I am getting H+ or 3G, which I can not go online anymore but on her phone, it still works.
Is is because of the version of the Mate 8 I am getting or the setting is wrong, please help!!!!

Probably wrong settings. Check your apn. And also make sure your phone isn't set up to just LTE only in the phones hidden menu

Update the software also and then check access point settings and set manually.

I check the updater, but there is no new update at all.
About the APN, I have copied exactly the same setting as my wife's S6, but still this issue.
Basically, whenever I am getting 4G above the bar, I can go online, no problem at all. But whenever it comes 3G or H+, my internet completely dropped!

I don't have that problem on T-Mobile with the NXT-AL10. I can be on one bar of HSPA and go online. There are two things possible. You have a bad phone with a bad radio or T-Mobile is doing work in your area and that's why you have no internet on anything other than 4G. T-Mobile was like that in my area two years ago until they upgraded. I would think it's the service. Try turning off VOLTE and LTE Cat 6 CA and turn on Data Roaming and see if that fixes it.

I was actually trying to help out on this issue, on another forum as well. One thing we discovered is that the settings for LTE Cat 6 CA are not on the L29 model.

Dumb question but you aren't using a metal case are you? Any aluminum case will degrade wifi and LTE to the point where it might switch over to HSPA+ due to poor LTE reception.

I have the L29 model. On T-Mobile, I was getting 3 mbps down and 1.6 mbps up. So I tweaked it around and enabled Data Roaming. Now I am getting 15 down and 9 up. Much more reasonable.

Recently had a similar issue. I copied over the apn from a tmobile device and that was the issue.
Try the 2 apn setup that should be default when you reset apn.

I have T-Mobile and it works fast but do yours say "4G" instead of LTE too?

Any updates on this issue? I'm still getting extremely slow mobile data speeds.

Suggestions on 4G LTE stick for use with Android HU and AT&T in the US

So I have a free spot on my family plan and was thinking I could just get a BYOD sim and stick it in a 4G LTE stick for use with my Android HU. All the ones I have seen has compatible miss all the relevant bands for US use, specifically for AT&T. Does anyone in the US have any suggestions?

I second this thread for Verizon.

So I finally got my dongle and SIM card and it is working and pretty much without any extra apps or root.
I purchased the HUAWEI E397 4G usb dongle 100M data card Unlocked 4G LTE MODEM B397Bu-501 - the important part is the -501 at the end they have several models with different band compatibility and the 501 was the one with AT&T compatibility.
On my Eonon GA2167 after I installed the stick the Cellular Networks entry showed up automatically in the options, I was able to edit the APN data there (you will likely want to be connected to wifi when you do this, if it's trying to provision data you wont be able to select APN data). I just copied the APN data from my phone and it worked. Using Cricket (AT&T).
I had some trouble getting it to work at first, it would recognize the USB stick allow me to edit APN and then connect to the network but I had no data connectivity. Eventually it started working. Not sure if this was after I copied every APN setting (previously I had just entered name, apn and the MNC and MCC) once I added the MMS/MMSC data and APN type it started working a little after that. But it could also been on the network side since it was a new SIM I had just activated hours earlier and had been inserted into 2 other phones (to help try to activate it).
Anyway if someone wants a stick that works on AT&T bands in the US this should work. The headunit only shows a 3G connection and reports WCDMA with signal check lite, but I think that's due to the firmware of the HU not being setup for 4G LTE, with a speed test I get about 8-9 Mbps down and 6-7 up, not super fast but I believe that is LTE speeds since HSPDA doesn't support uploads that fast, also the stick itself shows a cyan LED with is meant to be for LTE connected network. Either way its way faster than the wifi connected to the hotspot on my phone (not sure if its the wifi antenna or what but wifi performance is very subpar on this unit). Also it connects quicker on startup (and does so automatically) than wifi.

Thank you for this info! Where did you buy yours?
Has anyone tried this on a Joying_JY-UM135N or JY-UM135N2?
When I look at this listing on aliexpress, further down, it lists a number of "Network Bands", including the -501. How should I interpret this? Does the modem support all those bands, or do I have to specify when ordering? When I search for "huawei e397" on Amazon, it shows me a -53 version. Is this the same as the -501, or different? I'm also curious as to why the only hit I get on aliexpress is a listing in the Netherlands. ??

There are 5 different variants (2 off which offer CDMA/EVDO for 3/2G). They are all the same base stick but vary depending on bands supported.
This website details each on and the bands its supports: https://www.4gltemall.com/huawei-e397-4g-lte-mobile-internet-key.html
I bought mine from Aliexpress, you will want to make sure you specifically get the -501 for AT&T I believe the -53 supports some T-Mobile bands.
You might want to hold off till I can report more tho. After initially getting it working, it is proving to be inconsistent, I'm not sure if its a low power issue (I have ordered a Y USB cable) or something else. The -501 don't support the full compliment of AT&T bands and I'm not sure if that is the problem, it is missing band 2 for 3G and Bands 2, 4 and 12 (though 17 is kind of part of 12). I know in my area they use Band 2 for both LTE and 3G and I'm not sure if that is my issue. I seem to struggle to get it to work at home but if I am driving around town it will pop up and connect, FWIW once its connected its solid even at home until I disconnect and try to reconnect.
I will update has I make progress.

I have the exact same head unit and have the exact same issue, except I live in Australia and I'm pretty sure I have a spare Telstra (AU telco) dongle lying around, so it literally just works right out of the box? I thought these do support 4G, or at least I thought I saw it advertised like that (or maybe those are the Android 8.0 ones). What else have you done with your head unit OP, not many ppl it seems have this model and look to modify it lol.

It supports 4G speeds, when I get a connection in a 4G area on a band my dongle supports, the icon on the headunit shows 3G, but I get 4G speeds. I thinks its just a case of the limited firmware not supporting the icons and reporting for 4G but since all data transfer is handled by the stick then it works at those speeds.
A bit of an update. I bought a USB Y cable in case lower power was an issue, for the first 4 times after getting the cable things worked right away at boot up with no interference, that was a couple of days ago, since then it hasn't happened since. I am likely going to order a Momentum 313U, its AT&T branded and supports its full compliment of bands, but no idea on Android support. The only 2 things I could find about Android support was a generic listing on Aliexpress showing what appeared to be a 313U and stating it was an Android device and a Pilipino website saying it wasn't recognized by an Android Tablet (I think that's what google translate was telling me).
Failing that I will order a Huawei 303C, it supports the full compliment of AT&T 3G bands and is on the confirmed working list. No 4G but I think AT&T still has full coverage of HSPDA in my area along with LTE.

I have the exact same head unit from eonon and purchased the AT&T usb velocity stick off their site and plugged it into the USB port and it does not recognize it. The led is lit up on the stick but nothing on the head unit. It would be nice since this one has external antenna ports and supports LTE. Is there any software I need to install on the head unit?

Another update: I ended up buying a Huawei E303c stick, works on all the AT&T 3G bands and I haven't had an issue with it at all. max download speed has been around 3 Mbps but that is enough for voice commands, Pandora and navigation so I'm happy. I got closer 10+Mbps with the 4G stick, but I only worked some of the time (I think due to AT&T using multiple 4G bands in my area and the stick not supporting them all).
Anyway the Huawei E397 is up for sale and I'll suffer with 3G speeds.

I just got a Huawei E303c stick for AT&T. I plugged it into my generic Atcgfheny Oreo head unit and it shows no 3G icons. It blinks a blue light, but not connectivity on the head unit. Is there something else I need to configure? I can't find any settings in the menu.

S10+ Snapdragon 855 problems in Europe

I recently bought the S10+ G975W which seems to be from Canada. Apart from missing the mobile network and mobile hotspot switch which I managed to get trough ADB, there seems to be other issues.
For starters when I am on call and try to search the web - from LTE I go into 4g and the internet is a lot slower than on LTE ( it takes 2-3-4 seconds wondering before actually opening the page). I also cannot verify for sure if the VOLTE is working and network connection times aren't great. I live in Bulgaria and I have checked my provider uses 1800 and 2100 mghz combined frequncy for LTE. I have mobile data and it's fast while not talking on the phone. Can you please share thoughts on these problems and let me know if will have any other. I got this variant cuz i found it cheap in great condition.
