Please help

Ive just decided to change my number but I have completely lost all signal and connection on my phone, when will it come back?

daneb19 A few other things to note

The service isn't available between 9.30pm and 4.30am each day.
Your Active GoodyBag(s) and Credit won't be shown in your account until the new phone number is registered, which can take up to 4 hours.
You can only change your number twice per account. If done twice before you'll need to get a New SIM https://giffgaff.com/orders/mgm and Register a New Account to get a New Number.
If you've recently asked to transfer your number to or from giffgaff, you won't be able to change your number until a later date.

Usually it takes less than half an hour. You should switch your phone off and back on again occasionally.

Sometimes it can take a bit longer, in extreme cases it can take up to 24 hours.

I changed my number about 10 minutes ago, does that mean my connection will come back in 4 hours from now?

It should be quicker than 4 hours. As I said it's usually within half an hour but you should be prepared that it might take longer.

rebelyell thank you!
