I just changed my telephone number and I was wondering,what do I have to be able to see my new number to show on my phone ? Also on my previous number,I had the data blocked,so does that mean with the new number have that same block ?
Try restarting your phone, but sometimes changes on your account can take up to 15 minutes to kick in (sometimes longer if there's a system delay). And yes, the data will still be blocked on the new number.
Your phones internal settings may not change your phone number in its settings (so the old one will still appear) but on the network side, your number is changed and the old one no longer exists. Well, technically that number will be put back into the 'pool' eventually :P
