No signal using sim in Thailand

Hi, I have the same problem, I switched from pay monthly to pay as you go and since switching to pay as you go have found I get no network anywhere.

Hi @Abbyk1 

Welcome to the community.

When a SIM changes to pay as you go, it will not work abroad until it has been used to send a text message or make a call within the UK.
