So today I crossed over to Spark from VF.
The main reasons were
Esim support
Visual voicemail
Better coverage in this region
Possibly, if I’m ever convinced to join the club, Apple Watch LTE support
The process was easy and painless. I’ll get slightly less data for the sane money though. 10GB v 12GB per month. Probably won’t notice.
It took about six hours for No Service to appear and then I was straight on Spark. Thumbs up for a painless experience - a sadly rare thing these days.
