ATT now offering unlimited to any mobile any carrier

Just saw an ad for ATT if you purchase unlimited messaging you get unlimited M2M on any carrier.

Not that surprising.

AT&T's been really modernizing their US UMTS/HSPA+ network moving the transport from the cell sites to the core network to VoIP (Carrier Ethernet over VoIP). VZW is doing the same on their upgraded network /w the 4G LTE roll-out. (They only started this when they have moved recently the majority of their metro switching to VoIP which finished recently.)

Hint: Voice is cheap as molasses (think about VoIP) for ALL carriers.

T-Mobile's has had unlimited for ever, and Sprint has unlimited voice as well...

Let's see how long VZW holds out.

I believe that has actually been available for a few months now. It was introduced about the time they dropped their $5 plan for 200 text messages and added a plan with 1000 texts for $10.

Neither the 1000 texts plan or their unlimited M2M on any carrier interested me. I don't use either feature enough to justify them. And I think I actually had AT&T at the time of the plans changed and were added.
