This is a common question we encounter. Will my phone work or do I need to buy a new one? While the options are endless when choosing a device for your Global SIM 360 unlimited international calling card, there are some general rules of thumb to ensure compatibility and performance.

  1. The device must be GSM compatible 
  2. In the U.S: The device must be capable of 3G network speed (smart phone & basic/feature phones) For the BEST coverage, 4G is recommended.

Next, ask yourself how you plan on using your phone:

  • Is your GS360 enabled phone going to be your everyday phone?
  • Are you currently a subscriber to a CDMA network carrier?
  • Will the phone be used for extensive international travel?
  • Are you adding data? 

If your GS360 enabled phone is going to replace your daily phone, you may want to be consider adding a data plan for convenience. However, you'll notice that since our data plans are flat-rate roaming global plans, they're a bit higher priced than standard domestic data plans. If this is a concern, you may want to retain your standard domestic data plan and use your GS360 phone primarily for global calling. 

If you're going to retain your domestic plan for data AND standard calling, and add the GS360 card to a separate phone - you do have another option besides carrying two phones! Check out dual-SIM phones, enabling you to toggle back and forth between your standard carrier and your GS360 service. Slick!

Lastly, many new phones are already "unlocked", which means they aren't programmatically tied to any specific network. If your GSM phone IS locked, don't fret! You can contact your standard provider to inquire about unlocking your device, or there are dozens of unlocking services online.

If you’re not sure if your phone is GSM capable, inquire with your provider OR follow the directions below:

  1. Click the link "Will My Phone Work" - a lookup tool will pop up in a new window. Read and follow all directions below.
  2. Follow the prompts and fill in the brand, Model, Sub Model and Country for the phone you wish to use
  3. For the U.S: Enter AT&T as the carrier (or any other known GSM Network Provider) (Note: AT&T is one of many GSM Networks, and is used only for compatibility lookup purposes.) If your phone works on AT&T, the Global SIM 360 card will work in the device.
  4. You will see a checkmark if the device is compatible at 2G, 3G or 4G LTE network. BLUE = solid coverage. YELLOW = coverage, but may be spotty. For reliable service, look for the blue checkmark on at least the 3G level.  
  5. GSM compatible devices are standard everywhere else in the world.
