Roy RainfordMy wife has a low user SIM Pay-as-You-Go and put £10 on it just before lockdown. No calls made or internet used(knowingly) yet. The phone hasn't been outside the flat during lockdown and it isn't useable on our home network (according to Virgin). On trying to make a call yesterday outside and with a good Virgin signal, the Virgin auto voice said there wasn't enough left on the SIM and it needed topping up.
Could usage be due to apps left open which use the SIM and how do we check if that is happening? (and stop it happening).
