If you can make an out going call, but not receive incoming calls, the problem is not with your phone, its with your new carrier. Make sure you can make an out going call..
Next, we have to make sure your getting the right cell number. Dial 1-800-444-4444 from your cellphone. You will get a digitized voice reciting the phone number actually installed on your phone.
If the number given DOES NOT MATCH ( unlikely ) call your new carrier, identify your account and name/address with them. Verify the number you WANT to have with them,then tell then the number they actually sent to your phone.
If the number given DOES MATCH ( more likely ) than your number has not been ported over to your new carrier. The ability to keep your same number when you switch carriers is called Local Number Portability, or LNP.
The Public Switched Telephone Network "points" any incoming calls, regardless of their source, to your chosen carrier. Once your carrier receives your incoming call, it is routed through their switching centers to your local central office, where the ring pulse ( and the call) are placed on your individual circuit, be it a land line, or VO-IP.
That all works until you change carriers. Your new carrier must request your old carrier to release, or " port over " that number from the old to the new carrier. This must be set up in advance.Your old carrier gives your new carrier a specific date and time they will no longer handle any more incoming calls.This is called your LNP date. This is done within a day or so of your order. The new carrier creates a new circuit for you, with your old number, before their LNP date. This allows them to test your new circuit. If you bought a new phone, you may have had your old and new phones both working, but, until your LNP date,only your old phone would ring when called.
Now, on your LNP date, your new carrier is supposed to get a " hand-off " from the old carrier. This tells the PSTN to begin " pointing " incoming calls to that new carrier. Now, it is supposed to be seamless, the new carrier is supposed to have everything ready by the LNP date and time, so the switch can be "thrown", then your new carrier gets all your incoming calls from that moment forward. If your new carrier didn't completely port over your LNP number, or if your old carrier didn't release it, you are left with the problem you have described.
The solution is to call your NEW carrier. Even if your line isn't working right, only your new carrier can make the necessary changes to your line. Your old carrier wont deal with you, your new carrier must check with them over any porting issues coming FROM your old carrier. In any event, the solution is the same,you must call your new carrier to resolve this.
Now, all this depends on your ability to make OUTGOING calls right now. If so, this proves your phone or equipment ( if VOIP) is NOT the source of the trouble. Especially after you verify that you are indeed receiving the correct 10 digit cellphone number. Remember, even though it's a cellphone, you have to be able to receive incoming calls from regular landlines. Which means you must be tied in to the PSTN ( Public Switched Telephone Network).
This is actually a fairly common problem. The solution is routine, when I was a conversion technician, I would solve problems like this about 3 or 4 times a week, out of 25 or so service calls in the same week.
