You can get a Factura for ANYTHING you purchase. it's the Law. Golf carts have Serial Numbers, same as a VIN. ANY road legal vehicle can be registered and get plates. e.g. Quads.
I've heard that the Bosch is the best tankless. We have a Calorex w/ a small tank and a pilot. The small tank provides instant hot water and fires the heater which is able to keep up with the demand and provides constant temp. We use it as a backup to our Solar heater. Normally our Solar heater meets the need. We actually have two, one for the "house" and one for the master bath.
OK, you're free to do so. My problem was a congenital defect, impossible to fix w/o surgery. It was found via x-ray and MRI. Thorough diaganosics will tell if one needs surgery or can be dealt with via chiropractic. W/O good diagnostics any Chiro manipulation is just fiddling in the dark.
We travelled a few months ago, same form we've had for a few years. e.g. no RP box to check, two part form, give big (top) part on departure, surrender small part upon return.
In the USA when calling any phone simply enter the 10 digit number. Calling to Mexico from the USA enter 011-52-+ the 10 digit number. When calling to a cell phone you must add 1 after the 52.
Not a kitchen question. However, I think your SIM will work fine in the USA/CAN provided there's sufficient balance on it to pay the charges.
