That activation SMS has always been an international SMS, it isn't unique to your or that carrier. These things happen with carriers that are not supported. You should be able to activate on wifi with just the Apple ID and not the phone number.

Yeah, it does still work via email address, but a bunch of people are used to iMessaging me using my phone number. That was working fine up until I switched to using an iPhone. Then it stopped working. "my number" is my google Voice number. (I've tried switching it to my actual iPhone SIM card's #, but it doesn't help, and besides, that's not what I want.
I'm concerned that when they try to do so now (e.g. by replying to an old iMessage), their messages will just disappear into the ether
