A:AnswerYes, if you get the factory unlock model
Meaning the cel phone isn't lock into a contract when you buy it
That way it is not lock to any company and you can out your own working sim card in the country you are visiting
Note.
Make sure that first time you turn cel phone on
It doesn't have a sim card inside the phone
Because if it does, most likely that cel will be locked to company the SIM Card belongs to
A:AnswerYes, the Samsung Galaxy Note 9 does in fact, have the 512 GB storage option. You can purchase from your cell provider or you can purchase one at Best Buy, as I did.
A:AnswerNo. Simply does not. Buy it direct from your supplier. I bought it from Best buy thinking it would. But it doesn't. I've upgraded, swapped out SIMs, called ATT to to make sure it's enabled. Samsung did not enable it on the Best buy version
A:AnswerIt is unlocked I'm not sure what lte bands Claro uses but as long as the lte bands Claro uses are on the note it should be supported. This is a single sim model if you want dual sim you'll have to look on ebay or b&h photos might have some. Any microsd card should work regardless of brand just look at reviews before making your purchase.
