It wont let me on my phone it has came up Invalid USIM card


This is because you did not insert the correct SIM card. If you were provided with a SIM card when you bought the mobile, you can use only that SIM in the mobile. If you want to use other networks you need to unlock with the current SIM card. Unlocking can be done at www.mobile-unlocker.com within minutes.

Invalid usim card


unlock phones are so unperdictable...there may not be a fix for this issue..other then getting an AT&T phone....and even if u are able to get it to start working again more then likely u wil continue to have many more isses..mainly becuz of the network changes..for example....using 3g and 3g only...last year the AT&T network was stil using both 2 and 3g network and there was even a few 2g SIM cards being sold in stores...now it almost all 3g..which of course complicates many things...even if u own a 2g AT&T phone a 3g SIM card can be and will be used on that phone....with unlock phones running on the 2g network the issues with not having a SIM card where possible...it was still unstable when wanting to use data services....but voice services were possible...now with everything going 3g...its makes things alot more complicated with AT&T if using a phone without SIM cards...if ur phone has the fuction to beable to shut off 3g networking and run on 2g.(like the apple iphone has) then try that....good luck

My lg viewty invalid usim


Debbie invalid usim means its been barred by the network, so whom ever the network provider is for the phone you will have to give them a call and ask them to un barr as you have just brought it. We brought on off ebay at christmas on orange as we're on orange and had the same problem. We called them and they took the barr off straight away, no charge. Jan

Invalid usim


It sounds as though the phone is locked. When I had this happen to my Samsung A707, I had to send it back to Samsung to get it reprogrammed. (There are people who have bought the necessary hardware to interface with a mobile phone's OS, but I preferred Samsung themselves.) This was a free service (except for shipping) from Samsung. If you contact Motorola, they might be able to simply reprogram the phone for you.
