Sim stuffed?

[NN123]

Hey guys, I think my sim is stuffed coz I can't receive calls at certain times. Its not area network coverage coz I tried using another phone with MTN and that worked. I had this number for many many many years but I got the sim replaced about 3-4 years back when my phone was lost. Could it be that my sim is faulty, in that case just buy a new one, or do you think its another issue? TX

Doubt it's your SIM. More likely network congestion, dodgy signal or possibly the phone.
