porting your old number?

I don't know what you mean by "issues with their iPhone". Porting cell numbers has nothing to do with the phone itself - it's done at carrier level. The number has no effect on iPhone, or any cell phone model function. Any problems related to the # need to be taken up with your carrier. Not all #s are portable - check with your carrier first.

Delays in receiving SMS or voicemail alerts have nothing to do with the cell phone #, or whether it was ported. They can occur due inadequate signal at the phone end, again nothing to due with the #. Carrier volume overload is a culprit. I often had delays in SMS and voicemail with Sprint, but after switching to AT&T and porting that Sprint # to the iPhone 3G, I've not had this problem.

actually while that is true its also not true as can have some affect on if you just ported number it may not be fully complete as if it just done you can have several issues..


You could have where you can make outgoing calls on the iPhone but incoming calls are not working (cause still going to the old carrier phone). You can have where you can make and receive calls on the new iPhone but incoming text messages are still going to the old phone... I had this problem with my old sprint phone I ported number over to AT&T and gave my old sprint phone to a friend well he was still able to send text messages on the sprint phone and was having a convo with someone under my name and then next thing you know text messages were working on my new phone and I was like "who are you" when I started getting these text messages from people I dont know and then they would be like "oh quit playing Brian"


So I would give it 72 hours to be fully ported over.

Yes, sometimes there can be temporary delays in complete porting of the #. Again, *this is not an iPhone issue*. It is a carrier issue and can occur with any cell phone model.

I ported over from T-Mobile. I'd been told to expect that the move should be complete within 1 hour. By the time I got home from the nearest Apple store - about a 10 minute drive - everything, including text messaging, was working on the iPhone and my old phone was dead.

When I ported over from Sprint to T-Mobile about 3 or 4 years ago, it took about 5 or 6 hours.

72 hours seems way, way long to me. I'd say that if it's been 6 or 8 hours, call your carrier and find out what's going on.

I ported over from sprint. Everything was working within a few minutes...

I just ported over from Sprint and i get calls and can make calls.. Txing however is another issue.. I am getting sporadic tx's.. It has been 6 hrs now.. Any suggestions?

I ported my number a few weeks ago to ATT. It took approximately 3 hours. Once I received the txt message from ATT, I rebooted my phone and immediately received calls and sms to my new phone. I didn't have any problems with it at all.

The store rep did tell me to reboot the phone after I received the message.

Porting usually takes around a couple of hours, but the reason that the carrier gives you a 72 hour window is that they are cautious on their end.

All it takes is for the old carrier to release your number from their systems which is called MNP(Mobile number portability). Once thier systems release the number, it takes a while for the no to be registered on the new carrier systems. The no needs to be updated on the whole network which is very fast, but this might be affected by the traffic on the network at that time. That is the reason why the customer is asked to switch his mobile off and switch it back on so that the SIM and the IMEI no of the phone get associated with the no.


By the way, i worked for the UK mobile carrier O2 while i was doing my MBA in the UK and i am well aware of how mobile no porting works.

It can 24 - 48 hours for things like texting to begin working. The carrier generally releases voice first and the other services follow.
