Ported to T-mobile

Seems like it would be worth a call; I'd get the persons name and location and record the date/time.

This is the AT&T community forum (not tech support), we cannot look up your plan...

When I ported out all of our lines, my account shut down automatically.

It didn't lock me out of my account (excpet for a day or so, I couldn't use my number to log in, which was primary back then), and I could see my final bill, when it posted.

I had the opposite pro-rate experience.  I had ported really close to the start of the billing period, and they just never charged me for that period (I think I used maybe 3-5 days).

When I came back to AT&T, it was interesting, TMobile made a point of telling me that my bill would be pro-rated, and it was.   They locked me out of my account though, I just waited for the final paper bill...

@pgrey Nope you experienced exactly what is the expected behavior. Your bill wasn't prorated and you didn't receive a refund. The bill you had paid previously, actually covered service for the time you ported out and AT&T didn't refund you any money for the unused time.

An example:

Your bill cycle is the 10th-9th of every month. This means around the 12th of the month your bill will be available online and mailed out to you. Using AT&T's current cycle dates, your bill would e due on the 1st of the following month, so take the following:

You receive your bill on May 12th. This bill contains usage charges (such as overages, pay-per-use charges, etc.) for the timeframe of April 10th-May 9th. But the bill also contains monthly service charges for May 10th-June 9th. In your porting example you would've ported out, let's say, May 13th. In that case you would have had no service from May 14th-June 9th that you had paid for. You would've also had a bill in June with usage charges from May 10th-May 13th if applicable, but if not the bill would've been $0 (assuming you had paid the May bill as well and not let it go past due, etc.).

Now if you were an arrears billed customer acquired from another carrier, etc. your experience may have been difference, but if you were a normal postpaid customer, your experience would've been similar to what I mentioned above.

I included a sample from my latest wireless bill as an image. If you look in the top right corner you can see my bill cycle date is from 4/24/16-5/23/16 but when you look at the monthly charges section you can see that I'm paying for services from 5/24/16-6/23/16.

Hope this helps explain the process.

Yep, totally understand the process.  I had an upcoming month, when we ported, and we went 4-5 days into that month, which I never paid on.

I kept asking (chat sessions) for my final balance, and eventually someone just said there was no final charge for that period.

I went back, and double-checked, the last time I paid for my service was the month before, the month before I stopped service.

Maybe I hit a glitch or something...
