I read that if you remove the SIM and battery for a long time, it should restore your connection. i'm trying it now myself.

The only thing I can really think of is that ATT might be going through a transition right now from Edge to 3G.

The other option is to have a new sim card burned for your number. Call ATT, if need be put your sim card in another phone and call them, and have them burn you a new one. Does your sim card work in another persons phone?

Blackjack 2 is a windows mobile device 6 and it might need reflashed (set it back up). If there is no physical damage (you know no water damage, just has a few scratches, take it back to the store. you have 30 days to take it back, upgrade or new, its 30 days

I know this is not a fixya, but the only thing i could think of. try your sim in another device before u do anything

Bought a Lebara sim card today but when i put it in my phone nothing came up about lebara atall...is it possible that the phone is to old to recognise a new sim card?


Hello,
Hope you're having a good day
It is highly unlikely that a phone would not recognise a SIM card. It doesn't really matter how old. Please could you let me know your phone model so I could help you further?

No network coverage


Phone is not receiving any radio signal / received signal is too weak:
Confirm that network coverage is available where you are by contacting your service provider.

SIM card is not working properly:

Insert your SIM card into another phone
Note: Contact your service provider if you get the same message again.
Phone is not working properly:
Insert your SIM card into another phone. If the second phone works with the inserted SIM card, then
the problem is probably with the first instrument.

Note: In this case, contact your nearest Sony Ericsson service center regarding your phone problem.

Bought nokia n95 phone without sim card in ,but now i,ve put sim card in phone shows good signal but won;t let me phone out


  • PUK means "personal unlocking key" .
    The PUK code is asked if you enter a wrong pin 3 times.
    You need to call your phone service company, they can retrieve the puk code from a database
    for free.
    In your case you need to contact your SIM card phone provider technical support to unlock the SIM.
    The PIN and PUK are related to the SIM card, not to the phone.
    If you replace the SIM card with a different one, then the phone should not ask for the PUK anymore.
    Your rating is highly appreciated on this matter.

PUK code for my Sgh-a127 samsung


you can get your puk code by calling your phone service provider.
The phone doesn't have a puk cude, the puk is completely on the sim card and if you put another sim card into the phone it wont ask for a puk code.


Only people who can get you the puk code for the sim card are the company whos sim card it is, if its a prepaid the puk code should have came with it when purchased.

How can i unlock a blackjack2 to u my t mobile sim


Just call your carrier and tell them that you need your phone unlocked. Tell them you are traveling overseas and you want to buy a card over there. (rates are cheaper) They asked where I was going, I told them the Netherlands. Thats how I did it. Ask them to walk you through it though. The guy at t-mobile told me not to screw up the code when I put it in because it would lock the phone up or something. (don't know if thats true or not) I switched from AT&T to T-Mobile, then back again.
Hope this helps.
