Did you use sharp object to remove your Sim card from your phone Sim case?It might be that you have pierced and damaged the chip inside your plastic Sim cover.
Go and do a welcome back.

I use a sim tray

Deicide:
it's 1500 but you would need to take the old sim pack with you to the office, if you don't have that you'll have to get police report and no am not joking

oooh. I don't have that.

the sim card is working in small phone but not in my Android phone

immortalcrown:
Simply go to a Glo office to upgrade the SIM (a new SIM with the same number).

ok thanks. how much do you think it would cost?

it just suddenly stopped. no phone drop no water.
I have tried switching the sim position with me mtn still nothing. my main problem is that I used this sim for A lot of things including my bank account and it's troubling me. what do I do pls.? it's not from the phone cuz my mtn is working in both sim 1 and sim 2 but the glo is showing no sim.
