Bingo...dead on correct. International Calling is great for emergencies when not on wifi. Other than that calls to the USA (or to USA cell phones in SXM) are free. I've been using this method for years. Incoming calls from home connect perfectly.....texts are not a problem. Even calls made to SXM numbers are made at a minimal cost...definitely not ten bucks a day

Keep that phone in airplane mode unless you have an off wifi emergency. No need for a sim card etc.

Can't comment on the BSV wifi but I would assume it's decent
