Straight Talk to AT&T mobile-to-mobile minutes

[efparri]

All Straight Talk phones are not operated on AT&T. Some are on Verizon, T-Mobile or Sprint. Daleraver needs to clarify his message.

I would be using an ATT number ported to a ST ATT SIM, so I would be using the ATT network. What I need to know is if ST calls register as M2M for ATT customers. M2M is something that all ATT customers have. M2AM (Mobile to Any Mobile) is only for people with unlimited messaging plans and certain other plans. The people I intend to call using ST have ATT M2M, not M2AM.

Again, any clarification or anyone willing to call me for a moment would be appreciated.

I think efparri is trying to clarify what Daleraver said about the M2AM. Daleraver's wife might be using a ST phone that is on vzw, sprint, tmobile, which would explain why his bill is showing M2AM instead of the M2M that you are looking for.

My Google fu is strong. You can check with this if you are an AT&T customer.

CTRobinson: Yes, I think you are right. It might also be the case that even if she is on ATT, but has a M2AM plan, then any M2M calls on her bill would be labeled M2AM buy default because it trumps "plain" M2M.

MrBooMY: Yes, I am an ATT customer and I have used the M2M lookup. The problem is that I don't know anyone on ST, so I can't check any ST to ATT numbers. If some ST user with an ATT SIM wants to give me their number I could check it out. On the other hand, I know two people on Tracfone plans, and when I tried their numbers in the M2M lookup it said that they qualified. Sure enough, when I looked at my ATT bill calls to those Tracfone #s were labeled M2M.

I'm hoping the same is true for ST calls, and I would love it if someone could confirm it, or give me a call so I can see for myself.

Straight Talk is Tracfone it is also net10. If it worked for an AT&T tracfone it will work for straight talk they even share the same symbol on their phones.

I sent him my phone number. Hopefully it will fix his problem. I am AT&T straight talk.

I didn't realize my comments were incomplete.

My wife had been on my Family Plan with AT&T, and we ported her number to an AT&T unlimited sim account with Straight Talk. I doubt that where a number was ported from matters, however I imagine AT&T does differentiate between numbers that are using an AT&T MVNO or not.

BTW, she has had the service for the last 2+ months with no complaints or apparent change in service from AT&T previously. Trust me, I would have heard about it if that wasn't the case!

There is another fly in the ointment. When my wife calls my AT&T number from her AT&T number, the call is displayed as "M2AM." Maybe AT&T no longer distinguishes between in-network and off-network calls if you have the mobile-to-any-mobile feature on your voice plan. Someone without that feature has to report the results of calls between AT&T and AT&T SIM cards on Straight Talk.

I cannot speak about ST ATT, but I can confirm that calls to H2O and AV numbers (both ATT MVNOs) did show up as ATT in-network calls on my friend's ATT bill (they did not have the m2m feature).

Thanks for everyone's help. Just to report back, MrBooMY gave me his Straight Talk ATT SIM number, which I checked through the ATT M2M lookup from my ATT account and it said his number DID qualify for M2M calls. (Just to reiterate, I have only the basic ATT M2M plan, which covers ATT to ATT mobile calls, not the more advanced M2AM plan, which covers calls to any mobile device.)

A bit more information: over Memorial Day weekend I discovered that one of my aunts uses ST, but she bought one of the phones from WalMart and didn't know if she was on ATT or Verizon towers/SIM. I made a test call to her and checked it on my bill. It did not show up as M2M, so I looked up her phone number via an online lookup service and it appeared variously as an ATT landline or as "Ameritech RBOC." It seems that she had her landline number transferred to ST, which would explain why it wasn't operating as a M2M call. So I guess that's another caveat to add to the equation: be sure to know the origin/history of a number before assuming its a valid mobile number.

All in all, I'm confident that once I switch my ATT mobile number over to a ST ATT SIM, my calls to friends currently on ATT mobile will still register as M2M on their ATT bills.
