Questions about NTT DoCoMo USA
Is NTT DoCoMo USA still in service?
No. NTT DoCoMo USA no longer operates as a carrier — the service was shut down.
Can I still get an account number and transfer PIN from NTT DoCoMo USA?
No. There is no NTT DoCoMo USA support line to call. If the number still works, it belongs to whichever carrier took the account over, and you request the transfer details from them.
What happened to NTT DoCoMo USA phone numbers?
A number that was still active when the account transferred stayed with the new carrier. A number on a cancelled account was released back into the pool and cannot be recovered.
Can I get a NTT DoCoMo USA number reassigned to me?
No. Once a number is released it goes back into the general pool and is reassigned at random. There is no way to request a specific retired number.
Is the NTT DoCoMo USA name still worth searching for?
Only to confirm the brand is gone. Current account numbers, PINs and port-out steps live with the carrier that now holds the line.
Can I still use a NTT DoCoMo USA SIM card?
No. The SIM authenticates against a network that no longer provisions NTT DoCoMo USA accounts, so it will not activate on any line.
