Deactivated sim on swap

[turnipeater]

I have been having minor issues with calls dropping out and the customer service person I spoke to recommended a new sim. I said I would hold onto the sim and not bother swapping if the signal improved over the course of the next few days.

The sim was dispatched today and my current sim has been deactivated so I am now waiting up to 3 days for a replacement. No indication that this would happen and I haven’t clicked the link on the email to say I’ve got the new sim - is this normal? Seems like terrible service if so - no important calls when out, no 2 factor authentication I’m stuck!

It could just be coincidence and that you failing sim has finally failed completely.

Anyway, sims are sent 1st class so should be with you next day.
