It keeps saying inactive usim

a usim is like a mini computer sim, it is able to run things like video call and has a large memory capacity for example it can hold alot more phone contacts than the average sim, you could say a usim is like when you upgrade the memory on your pc. If it is inactive , if it was working before you will need to contact your network provider, explain it has gone inaactive and they should be able to sort it over the phone for you. I hope this helps mate

No, its not the signal problem. It is infact ur SIM problem. U will have to call back ur network provider to resolve this. an inactive sim is always as good as dead sim. Ur SIM automatically gets inactive by ur network provider if not used (switched off mode) more then six months.

Hope this helps.
thanks

to solve this issue i find throwing it at hard wall or sterdy object seems to fix it for about 3 days before i try and make a call or skype call then it dies again i have had the phone repaired 3 times!!!

i am using sony ericsson c510i -first inactive usim problem and next secend insert usim problem so please solution in image view

You need to go to a phone shop that stocks 3G sims. Get a $10 sim (a blank free one probably will not work). You didn't say whether you were on a pre-paid sim or a plan. Anyway call 3G and ask them activate it. Get the number off the sim before you ring them. They will need U to quote that. hope it helps :o)

sir you will have to go to your service provider for the solution to your problem.......they will get you a new SIM and this should help you......

Hi,
