it says no sim or sim error
I have the same problem. When placing a call it says no sim or sim error but data works, help please.
The problem usually has to do with the copper connectors on the sim card getting dirty. To fix it just follow the steps.
My IMEI number is available. Baseband available too.
I get data connection but can't send text messages or run any USSD code i.e. *556#, *426#, etc. which I can use to recharge my airtime.
I've tried your prescriptions as above but null.
What do I do next?
Thanks in expectation.
