The SIM card is hopefully fine, but after registering it to my O2 I found that it has been activated for 14 days through a foreign device. What Alza did with it before is a mystery to me. I won't solve it, but I don't have a pleasant feeling about it, next time I'd rather go straight through o2

SIM card purchased in November 2025 and according to O2 it is already active from May 2025, so I don't understand it now that I have unpacked it. Somewhere 7 months are missing.

A whole year of peace. I have 100 Gb per month, so roughly 3.3Gb per day, which is fine with me. Sim router with ups and there is internet even without power. Nothing crashes and it's running. I'm satisfied.
