How are MVNOs able to offer a lower price than the carriers? I was interested but didn't switch because I was worried they are selling my info or something.
And in reverse, better brand recognition/(impression of) service quality allows the network operators to charge more and still get customers, the MVNOs need to be cheaper to compete with that.
I ported my landline to Page Plus in the late 2000s (which took over a week). I still have that number, and I have never spoken to a person when porting it between MVNOs (always over chat or email). My last port to Red Pocket took two days to get right. This can be a frustrating procedure, and many people prefer the major carriers for in-presence customer service for issues like this.
I have repeatedly switched between Verizon and AT&T when necessary due to phone hardware or coverage, and MVNOs usually allow this to be done (a limited number of times) through automated simcard changes with no customer service interaction.
The one surprising thing about my recent move to Red Pocket is the lack of voicemail in the included plan (it's available with a surcharge). I'm not certain if I miss it.
