[Q] sim card issue - Galaxy S II Q&A, Help & Troubleshooting

i am facing a very strange sim card issue.
i am using a demo sim card.. ( a demo sim card is a special sim card that is used to refill the prepaid account of a particular carrier... --this is with respect to india)
The issue is --- i used to refill the prepaid accounts of many people using my sim card.. this was running successfully on sammy's unrooted GingerBread firmware..
but recently i rooted my phone & upgraded to Bezke's Milestone 4 ICS ROM...
Since then i am not able to use that service.. (i.e. i am not able to refill any account)..
has anyone else faced similar issue.... or can any one suggest me a solution..
please help me..

Don't know about demo SIM cards..
But did the phone had a valid IMEI number before you rooted? Has it changed after rooting? If yes.. then search for lost IMEI thread...
If it hasn't and you don't find a solution, try flashing back a stock ROM.. and then see if the SIM card works..
I also guess you can still use the SIM on other cheap feature phone.. Don't see a sense using it in SGS2... Just for topping!!

[Q] No UIM card on Huawei C8650

Hello,
I bought the phone Huawei C8650 from the USA, but it seems that it requires a UIM card instead of a SIM card. Is there a way of running the phone with a normal SIM card? I was thinking of installing a different Android version on it, because it is running android 2.3.3. Any suggestions what to do?
I am using this right now. UIM is the card for CDMA (a counterpart of GSM), so sorry but there is no way to use SIM card on it. It's like you cannot install IOS apps onto android cellphones.
PS: I think in the US people use OTA. There is no need for UIM if you are a customer of a CDMA network like Verizon.

[Q] New card - no sim

Hi there
I have HTC Mozart phone from 1 year. The phone is unlocked, unbranded.
I use our mobile operator (mtel).
But get new sim card (same mobile operator). When put new card- phone notify that no sim card inserted or invalid. When back old one- say no services (it is normal because it is stop from operator). When put other card - phone notify the same- no sim card inserted or invalid.
Is it possible old card lock my phone some way?
Any idea wtf?

It is possible for the operator to lock your phone trough the zune updates.
That's what happened to me. So if you have updated it that way its most likely that it has happened to you too.

[Q] SUDDENLY SIM card not detected - Micromax Canvas HD A116

GOod day friends,
I have a Micromax A116 thats almost a year old.
2 days back, Suddenly the SIM card is not getting detected.
The same sim (BSNL 3G) has been used for almost a year now on the same slot and suddenly it has gone non-detecable....
( then i checked the sim on to other mobile and it was ok. )
I changed the SIM from Slot 1 to Slot 2 ....still Card not detected......never used Slot 2 for any purpose....
So i decided it is really not a hardware issue but something to tweak ..........
I tried checking for IMEI number and it was getting displayed with #*06#
So IMEI no. is intact.
Recently i had changed my memory card from 4gb to 16gb .... i guess some related to it would have caused the trouble......bcz i FEEL that was the exact moment the sim cards went non-detecable.
So i changed my back to my old memory card and still the problem..........
SO i request some body who is aware of this issue to guide me to resolve this issue....
Thank you in advance
Regards
Thiagu
factory reset
