I really wish someone can help me out.
I'm currently on O2 Sim Only Unlimited 12M 20GB and I have just noticed on My O2 app that my contract should have ended on may last year.
I have checked my upgrade options and there is not the tariff 100giga for 20£.
I was wondering If I am able select this upgrade from the home page will it works as a normal upgrade or I do not have this tariff in my upgrade options at all?
One more question, if I am happy with my current sim only contract it will renew every month or I will have to have the same tariff for one more year?
