There's been a fair amount of blowback on these forums in regards to Roam Mobility's migration to LTE data
. If you didn't know, users have had to pay a $1.95 upgrade fee per SIM for LTE access in the U.S.A. And as far as I know, that upgrade is mandatory. Perhaps more contentiously, access to LTE requires that a new phone number be assigned to your Roam Mobility SIM.
What no one seems to be talking about, however, is the new service itself. I think it's pretty great.
