My new SIM has been posted to my home in the UK while I'm away in Europe for at least another month. I don't want a disruption to my service, so need to swap the SIM ASAP. My flatmate can send the new SIM to me, but can it be activated overseas? If not, can my flatmate activate the SIM in the UK (on another phone) and then send me the SIM so that it then works on my phone?
Do you mean that it should work to do the activation on my phone overseas? Roaming is no problem, but to activate, I'm supposed to send a text to a 6-digit number to signal that I'm ready to do the swap - will that number work from overseas?
