I have a TYTN II on the Orange UK network (Pay Monthly). The phone is unlocked and works with a O2 (Pay as you GO) SIM on the network.
I recently bought the following Dual SIM Adaptor :-
http://www.m-99.co.uk/Mobile_Phone_Twin_SIM_Adapters/mobile_phone_twin_sim_adapters.html
I cut both my SIMS and tested them on a Nokia. The SIMS work fine in the Nokia, I can select SIM 1 or SIM 2.
On plugging the adaptor into my TYTN, the O2 network works fine.
On switching to the Orange UK network the phone shows signal, but after approx 15 seconds the network shows no signal.
When trying to access the SIM Manager during this 15 seconds it does state that the SIM is initialising.
The Adaptor works fine on a Nokia but not a TYTN II. Any Ideas ??
Perhaps it requires different hardware? On the site you have to choose the model ..
Bought one from another site and same problem.
I chose the TYTN adaptor.
I'll try a different ROM.

Maybe you have to turn the radio off before switching from one sim to another.
Have you set it to GSM network type ?
Go to: Settings>Phone>Band (you will need a working sim installed to enter phone options)
I had a bunch of dual sims that worked great on WM PDAs, sold um all.
Your problem sounds like the Orange SIM is not connecting well.
One trick that can work well is to place the Dual sim adaptor (SIMs loaded in adaptor) on a flat surface PCB side down & apply even preassure over the top with your thumb (Give it a good hard squash)
This normally cures it.
Another option is to swap the sim positions & see if Orange works in the O2 slot (this will prove sim terminal connection problem)
Thanks Mister B,
Went to Settings>Phone>Band and switched from Auto to GSM. All works fine.
Cheers
DUAL SIM Not working on Treo 750 WM 6.1 GSM phone
The Dual SIM Adapter boasts of not needing to switch off to switch between SIMS. But it shows only default SIM 1 and not the second SIM. My Treo 750 is a unlocked WM 6.1 GSM type. Can anyone help pls?
No 1: follow tip in post #5
No 2: remove sim adaptor from phone place it on a flat hard surface with the PCB board facing down & roll your thumb over the back of it with reasonable pressure & then retry it in your device.
Some of these adaptors need a lot of patience to get working due to poor contacts between sim cards & adaptor.
You can also swap position of your 2 SIMs which will help fault diagnose the issue.
Hi guys ,i hope u can help me with this..
recently i just got the grand 2 like 2 months ago...when i tried to activate mobile data (of sim1) i had a problem ,it's not working,
I tried to trouble shoot the problem by changed apn's and stuff like that with the cust service,,nothing,
however,when i remove the 2nd sim the data of the sim1 ( which i want to activate) starts working ,I always make sure that sim1 os on wcdma and sim 2 mode is on gsm...i had sim 2 as clipped micro sim,however went to store and got a brand new micro sim to see if the clipped one was the problem ,nothing changed ,also swapped their position and placed sim1 in place of sim 2 and voice versa ,nothing happened same problem ,,,I also sometimes get a message saying:
the mobile network will be unavailable until you restart with a valid sim card inserted ,,and only the restart button available and u can't override it by pressing home key or anything so restarting in this case would be mandatory ,,that's why i chaned the 2nd sim card but nothing happened.
now i still can't get mobile data on my neww phone from sim1 and it's driving me crazy ,i think it's a software issue but am not sure cuz when i go to sim card manager and change the data service network to sim2 then put it back on sim1 ,some times the H+ appears and it works ,but not always and not for a long time,,,,,so the problem is between mobile data and dual sim functionality ,do u have this as a common issue ???,,please help
again ts steps i made:
1-re positioned sims in place of each other.
2-changed sim2 into an original micro sim instead of the clipped one i used to have.
3-i reset phone to factory defaults but same problem appeared

I think it is a hardware issue. take it to the service center and insist on getting the issue sorted out as they will try to fob you off with some excuse or other.
all the best

Hi.
I was searching for a solution for exactly the same problem.
I have the same phone as you and I get this to work if I select the option to allow Roaming, even though I fix the network operator to my provider's network. Strange but it should work.
Leifur.
m too facing the same prob in my grand prime 4g... i bought dis sum 10-15 days ago... plz help me to solve dis... othrwise i hv to use it as a single sim... any suggstion...plz help
Sent from my SM-G531F using XDA Free mobile app
Here is the best solution: I faced the same problem and fixed it doing the following...
First restart your phone, when you do that you will see the sim configuration settings screen appears at the boot time and allows you to choose which sim card to use for the Data Service Network... it has three options
1. Sim1
2. Sim2
3. Data service is Off
the third option is active and set by default which is why my cellphone was not working internet and i changed it to Sim1, and it worked perfectly so you have to try it again and again by changing the sim card in their slot... hope that helps!
my 4g on this phone is stopped working and there is so much hang problem in this phone, don't buy it, I did factory reset so many times in this phone to remove my problems but they remained as it is. I am writing about samsung galaxy grand prime 4G phone, model G531.

Hi all,
Does anybody have a problem with data on the second SIM?
You can choose on which SIM you want to use data.
It works on SIM 1 but doesn't on SIM 2.
APN settings are 100% correct.
I have tested the SIM in another phone and data works there.
I've now ordered a nano-SIM to micro-SIM adapter from ebay to test it in the SIM 1 slot.
Quite annoying.
Maybe bcause sim 2 slot works only in 2g
Seeing that no one can help me with the problem below, maybe some one knows how to add 1700/2100 to band frequency to 3G?. that mite increase speed?
Problem, Can not get phone Mobile network to use 3G/4G/LTE, Only EDGE will show for each Sim Card Signal.
Details on phone: Vibe 5K Plus, Build A6020a46_S105_161124_ROW, Type PA2R, Model 0117IN.
Qty 2 T-Mobile sim cards: Slot 1 for Data Sim card, Slot 2 for calls & text.
Have taken phone to T-Mobile service store, and spoken to T-Mobile global support on phone about problem with not being able to use 3G/4G/LTE.
The APN settings have been checked with T-Mobile as been correct.
When looking at phone Settings, SIM Management displays Default 4G/3G Subscription[/B for the Data sim card in slot 1.
Also Enhanced 4G LTE Mode is turn on
When looking at phone settings, About PhoneStatus/Cellular network type, displays T-Mobile EDGE in sim card slot 1.
Other T-Mobile sim card in slot 2 displays GSM
When looking at phone settings Mobile Data Mobile Network settings, T-Mobile data sim card in slot 1 displays Preferred Network Type GSM/WCDMA/LTE auto.
Other Mobile Network settings for sim card in slot 2 for calls and text displays GSM only , this is greyed out.
When Data sim card or Call & text sim card are turn on in network, Both only show EDGE and is really slow.
Hello,
I bought X Compact (F5321), I inserted a nano sim card (let's call it "A") and it was working fine
So then I tried to insert a (cut down to nano) standard sim (let's call it "B") and it cannot register to the network (though it's being recognized).
This same sim card (B) is working perfectly on a lumia, an iphone 4s and a couple of other smartphones (wiko sunny, and energy lite).
The contract of A and B is both on bmobile Japan, but B is on a voice-only contract (no internet option).
I installed a custom rom and rooted the phone following this guide:
https://forum.xda-developers.com/xp...oot-automatic-repack-stock-kernel-dm-t3301605
I then added some other bands working for Japan (all the bands correctly showing in the "Configuration" screen) and I was able to select [JAPAN BAND] without any error whatsoever, and still no signal at all..
Any idea why card B isn't working?
Many thanks in advance for any suggestion
