I have just upgraded my sin only contract. I am waiting for a new SIM to be sent to me. I have noticed that now my old SIM which is still in the phone is now not working and I can't call or text. Is this normal? I would have thought the old SIM should still work!
Indeed it should. If, by "SIM only upgrade", you mean a change of payment plan - this doesn't, of itself, necessitate a change of SIM unless there is a fault with your existing one.
You might even find your new plan is already active on your existing SIM and the "replacement" one can just be treated as a spare and filed accordingly.
Can you explain what you mean by your current SIM no longer working?
