Hello everyone !
First i have to tell you sorry because i don't know everythings about the phone rooting and all of that but i know some!
I bought a phone in Thailland , the True Smart 4g Max 5.0 and i would like to use it in France, i watched everywhere on the web
and i have try some many tutorial but i can't root my phone and i can't install new rom,
when i put my sim (Operator FREE Mobile) in the slot 2 (sim 2g) i got full bar network and a E next to it (Edge i thinks), so i try to call and the phone tell me sim 2 is locked pls use sim 1 but the sim 1, its write slot 1 True H and nothing appear when i put my sim in.
I read on the web we have maybe not the same frequence network Thailland/France? Is t possible to change the frequence of my phone ?
Thanks you for all your futhur response

Okay, so - first off, let me give a quick intro: I am really sorry if I post this in the wrong forum. I AM a noob.
I've been a long time reader (and a very happy user of the great knowlegde base and ROM development here on XDA!) and this is my first post. I'm not anywhere near to be a Linux/Android wizard but on the other hand I have gotten S-off and root on my Wildfire S, have tried different ROMS, link2sd, modified GPS files with root explorer etc. That's kind of my level.
-------
So - now to my question. Please be patient with me, it's hard for me to explain in simple terms and english is not my first language. I WILL get down to facts and numbers.
I've decided to move to a more powerful device and I have just bought a Galaxy S II, bought unlocked from my provider. So basicly all I should have had to do when I got my GS2 in the mail was to pop out the SIM card from my Wildfire S and pop it in the GS2 and it *SHOULD* have been working. Problem is - it works 'kinda'. Yes - it works in the worst way - from time to time. I am puzzled!
I get very bad reception and most times NO reception - no signal.
The SIM card does not get rejected by the phone as if the phone was locked, and if I go outside I CAN get a signal, and I CAN make calls. Sometimes I have been cut off. Now I'm not talking about me not just getting data or GPS signal - I'm talking about 2G GSM signal for just making calls and texting. But outside downtown I HAVE had the H+ sign for data appear and I HAVE downloaded from market with the troubled SIM card.
So one would think that the antenna/modem(?) in the SG2 does not work properly. Well - I got me a pre-paid SIM card from the best covered provider in Denmark. I pop the SIM card in - I get a fine signal. Data and GPS works well, calling and texting - no problem!
I have tried 2 other SIM cards from my provider from friends phones - CBB using the Telenor network - and results are the same. Very poor signal, sometimes no signal.
So here's the facts from inside my appartment in a larger city well covered from several providers in Denmark:
- SIM card from my provider in Wildfire S gives me a signal between -80 and -90 dBm and 10 - 15 asu. All functions work, GPS, 3G data, calls, MMS, texting.
- The same SIM card in the GS2 give me at best around -100 dBm and 5 - 6 asu but often drops to -111 dBm and 1 asu. I have seen -113 dBm. Useless.
- SIM card from another large network provider gives me 80 - 95 dBm and 8 - 15 asu.
- I have checked if the phone is locked - it is *NOT* SIM locked.
Remember - this is all in the same place in the same chair in front of the same table. If my provider had a poor signal Wildfire S should be affected as well.
Can my SIM card from my provider somehow be incompatible with the SG2? I have of course called my provider and explained all of this. They had NO clue why it happened but would mail me a new SIM card before doing repairs.
After a factory reset Wildfire S will pop up and ask me what provider I am using after detecting SIM card (select SIM service prompt). SG2 will do the same thing on the pre-paid SIM card - not on the SIM card from my provider. Does this mean anything to any of you?
Is there a way to determine the type of the SIM card in the phone? I would like to know if the two SIM cards are of different types using different technologies - whatever - so I could determine if the SG2 was not compatible with my providers SIM card.
Model: GT-I9100

If you are still with me this far - thank you very much!
I had a somewhat similar problem that I solved just this morning....
Here in Costa Rica there are now 3 carriers, ICE which is state owned and two private carriers, Movistar and Claro.
I bought my S2 unlocked from a fella that bought it from Claro. The chip I was using was an old GSM chip that I was using in my previous phone. I had data connectivity but it was slow and calls dropped constantly with my chip. I have another phone with a brand new chip and when I would use it all was good. The old chip also had an R on the signal for roaming most of the time, and it always thought it was roaming when I had market enabler programmed to fake at&t so I could get to certain apps.
But this morning I went to my carrier and got a new chip and all is good.
Bottom line, go to your carrier and ask for a new chip. There may be something in the programming not optiized for the phone you have or the current network
Actually, cdzo72 could be right.
Check how old are SIM cards you were using.
Prepaid one should be no older than 1 year, meaning new tech included.
Try to find someone who recently got new contract with same provider U are using (CBB) or at least new/replaced SIM from them.
Few years ago my provider forced me to change SIM card on renewing contract since SIM "is no more fully compatible with new technology in modern mobile phones", whatever that means.
Thank you for your time.
I have a new SIM card waiting for me in the snail mail tomorrow, and I hope that it will work.
My current SIM card is 3 years old, and when I got it, it was on the same occasion as Bodisson - I got a new Nokia, and my old SIM card was not compatible with the new phone.
If this is the case however, I cannot help to think about why my Wildfire S works without any problems at all with the current SIM card. One should think that the two phones use the same technologies.
Oh well - if it doesn't work with a new SIM card the GS2 is in for repairs on monday.
The worst thing is that I have had the phone for 10 days and I feel as I did when I was 8 years old and didn't get a Commodore 64 for christmas! I want to play with my new toy!
Hello developers.
I am amz. In dire need of your help.
Ok so i have a new mini
I turned it on n it would jus turn off if I used apps. I got a new battery. That stopped.
I then try use Internet it works only on G and E but if I go to 3g or Lte. .H will never come on. Can't call it says not registered on network only on the higher bands not gsm.. It's a 4G sim it works perfectly in my old s5 mini and signal is excellent here. I got new Internet settings too. G n E works why the he'll doesny the other bands register on network? Imei shows its not blocked either. I'm in the UK on EE. I cannot understand. I have all the OTA updates. Can u tell me if I can fix it by doing something thro service menus or anything also all sims do the same in this phone. I don't have a pc to change the rom. Could I do it through a external SD card.
Please I beg of you help.
Dear Community , I’ve just bought a P9000 smartphone and I’d like to ask a question: as far as I know this dual SIM phone can not support 4G (or even 3G) when both SIM cards are inserted but to me the only way to have 3G or 4G capabilities is to insert the SIM card in slot 1 (the outer one, the same slot of t-flash memory expansion)… Is this behaviour normal? I thought that , with a single SIM card inserted, didn’t matter which slot was used to get 3G or 4G working on phone, and this is a severe issue because if you want 3G/4G capabilities you have to use slot 1 and therefore no more t-flash into the phone… Please, could you help me? I tried with engineering mode (BSPTelephonyDevTool) but no joy at all... Thanks in advance, best regards.
I have always had my sim (Three UK) in slot 2 as I use a 60GB SD card and I have had no problem getting 4G tbh. Altho the 4G connection was never really as fast as I expected & very ocassionally it wouldnt attched to a 4G connection in an area with 4G (but this was kinda very very rare)
Sorry I dont have a solution to your issue, but on a side note I have just installed the Andriod 7 Beta to test it out and I can confirm that the 4G is outstanding on that, even the 3G is way faster with a much much better signal - better than I have ever experienced on any other ROM to date. (same with the GPS, its spot on)
What network are you on & what Stock ROM (I'm assuming your using stock with you just buying it) are you using? the latest Stock?
Thanks for prompt reply, to be honest the phone belongs to my sister... Anyway, the P9000 is on TIM (Telecom Italia Mobile) network operator and android version is Marshmallow 6.0. At the moment the issue still remains, I think that she'll be waiting for Nougat 7.0 to come on OTA...
Hello everyone.
I have one or two little questions about the phone. I have this phone since July and I would like asking about few f*cking issues. I have the H930DS with the Boombox ROM and have faced the same issues with the lastest 21* Official ROM.
SIM A France with Roaming ok - SIM B Switzerland. I live in Switzerland.
------------------------------- DATA SIM A - Calling with SIM B -----------------------------
-> no internet while calling
-> sms cannot be send with SIM B
-> poor signal with sim B, very oft no signal
------------------------------- DATA SIM B - Calling with SIM B -----------------------------
-> internet ok while calling
-> sms cannot be send with SIM A
-> Very good signal in SIM B, poor signal with sim A
My Problems with signal quality is also when I make no call. I don't understand why is so... Make no sens. I have oft the problem with no signal in SIM B and when I choose SIM B for Data, signal is automatically better....
Faced you this problems ?
Thanks you.
Anyone with other/previous Dual SIM devices can tell a same story ?
The most seldom Android devices have dsda (dual sim dual active), afaik the H930DS is dsds like many devices (dual sim dual standby)
https://gadgetstouse.com/news/dual-sim-dual-standby-and-dual-sim-dual-active/8985
That at least partially might be able to explain it,
also living at the border and roaming with 2 different country SIMs is supposed to be quite bothersome I read back some time.
No idea if it's supposed to have improved
Thanks, I had no idea about this active or standby mode. This is annoying... But that's explained not the problem with signal strength... I have no idea how is it possible.

what connection tech / speed are you using for each different SIM ?
if I remember correctly there was also an issue with only one SIM being capable of using 3G or LTE at a time and the other being limited to 2G (or similar)
so that could be one explanation of it.
Haven't looked into that kind of issue yet since I don't have a dual SIM device
Hi I'm buy pixel 6 about 3 month but never insert SIM card just now I need use SIM card can't use 3g/4g/5g it's use about 5-10 sec the signal is lost
I upload video on YouTube
if anyone can solve thank you
Bump
Have you tried another SIM from a different network?
