Testimonials
I’ve been working with Belmont Telecom for over 10 years. I’m impressed by the quality of customer care and attention to details.
Ken Griffin
CEO of Teleloop
So glad I got this card before my trip to Europe and was able to get it configured and tested before I left the US. From what I understand, to get a SIM card in some places in the EU requires a lot of paperwork, ID checks, and a bunch of hassle. Definitely don’t want to deal with that immediately after a long trip just to get there.

If you’re traveling or and EXPAT residing overseas and need an avail stateside number or even more importantly a number that you and your bank can use for verification of banking matters, One Sim Card is the way to go. Not only does this sim card work but the tech support and customer service works fast and efficiently.
