OneSimCard Expedition International SIM Card for Travel in 200+ Countries with $5 Credit – Data from $0.01 per MB. Compatible with All Unlocked GSM Devices & Phones

Setup is relatively easy. Dialing a number is only a bit weird - ie you have to dial the number, then wait for a callback to actually connect the call. The wait is not long, only a couple/few seconds. It just takes a bit of getting used to a phone functioning this way. But it is a great solution so far. Give me the flexibility to take a sim with me and have it already active and using the same number through an entire trip through multiple countries rather than switching sims every time I land. So far so good!

I ordered this SIM and it actually arrived within a week to Bulgaria. Amazingly fast delivery and it's is very easy to install. This is a great product for people who travel internationally.UPDATE-If you need to receive bank codes for authentication, this will only work if you purchase an additional phone number for another 90 a year. This is not stated in the description of the product. It's kind of a bait and switch scenario. Even once you pay the additional fee you can only receive codes, you cannot reply to anything so when the company sends you a message to accept texts, you cannot reply.

This sim card worked very well for me. I traveled to Europe this summer and visited 4 countries - One Sim worked flawlessly in all of them. The local carrier was immediately identified in each country. No problem making or receiving calls. No problem with data. The One Sim VOIP and OneSim Card Direct apps were useful as well. Given the flexibility to use one sim card across many countries, and keep one number, I found the rates very acceptable as well. Data packages were definitely more favorably priced than the alternative offered by my US carrier. Hassle free use of the card does require some reading of the information available on the One Sim website, but the info is there and the card works as advertised.

This SIM card won’t work with United States banks like US-Bank to register your SIM card phone number the bank would give error message saying the number isn’t a Mobile number. You can txt fine with regular txt to friends and make and receive call’s!

Worked good. Over priced, and way to complicated to add more funds. I'll try MobalOne next time.

If you follow the included steps it's easy to do. I would recommend setting up your PEN (Personal Extra Number) after you've set up the card and then when you charge the card later. Everything on my GSM Samsung Note5 works great.

I bought this card because I wanted to set up PENs (Personal Extra Numbers) for each country in which I need a phone number so that I do not need to keep a local contract running in each countrry. At the moment I am still testing, but so far so good. One point worth noting is that if you need to receive US bank codes for authentication you will need to purchase an additional specific US PEN number which costs extra.

The OneSimCard is an affordable pay-as-you-go option. This is the second one we've purchased. The SIM card has multiple perforations for installation as a nano, micro, or mini sized SIM card. Simply detach the appropriate size for your phone and install. It works right out the package. The website is loaded with helpful information for options and troubleshooting, although it is not the easiest to navigate.
