This could be very appealing for users of Canadian MVNOs like SpeakOut and Petro Canada Mobile. These MVNOs use the Rogers Canada GSM network but they cannot roam in the US. Also the standard phones they sell are unlocked.
So Canadians who want to be able to use their SO/PCM phone in the US could use the new UM+ SIM instead of buying a T-Mobile or AT&T SIM. Even though UM's airtime is more expensive there is no need to buy at least $100 of airtime from T-Mobile in order to keep a US SIM and phone number alive for 365 days. They would also be able to use that UM+ SIM outside of North America providing they have a quadband phone.
This development is certainly appealing for me because I already have a UM+ account and I don't travel to the US often enough to justify buying a separate T-Mobile SIM.
