7. Troubleshooting Questions
    • I just arrived in a foreign country and my phone is not working, what should I do?

      If you left your phone on during your flight or cruise then you should fully power down and restart your phone. Once your phone powers back on it should automatically select an available roaming network.

      If your phone is not a quad-band phone, please make sure that the bands of your phone are those required in the country of your travel. You can look it up here.
      In some countries like in USA turning off 3G mode of the phone will make it quicker for the phone to register on the network.
8. Ordering Questions
    • Can I use OneSimCard service if my phone is locked?

      Yes. There are a few options available if your phone is locked to the carrier that sold you the phone.

      • Try contacting the carrier to see if they unlock it for you.
      • You can purchase a travel phone bundle with the SIM at

                 http://www.onesimcard.com/international-cell-phones/

      You can purchase a MI-FI device with aOneSimCard SIM card (Universal, Expedition or DataMax physical SIM card) at http://www.onesimcard.com/international-cell-phones/. The Mi-Fi device will provide your locked Android or iPhone with mobile data over Wi-Fi connection that you can use on your phone for Voice and Texts using SIM VOIP app, as well as data for web browsing, email, GPS navigation, etc.
9. Troubleshooting Questions
    • I have an iPhone and am receiving charges for SMS sent to a UK mobile number 447786205094. Why?

      This is a known issue with Apple's Facetime and iMessage applications on Apple iPhone  devices. We recommend disabling Facetime and iMessage so it will not be able to automatically send SMS to this 447786205094 number. Any SMS sent to this number automatically by your phone can not be refunded by OneSimCard. Additional questions regarding iPhone applications and how they communicate should be directed to Apple Support.
      You can learn more on the Apple Support web site:

10. Troubleshooting Questions
    • The battery in my phone does not last long? It got fully drained during the flight to Europe. Why?

      There can be a number of reasons why a battery does not hold a charge. Excluding the possibility of it being a faulty battery, there is another important factor to consider. If your phone is not registered on a roaming network, the battery will drain very quickly as the phone is constantly searching for a network to register on. So, if you get on a 6 hour flight and do not turn the phone off, or put it into airplane mode, by the time you land at the airport your battery will be drained and you will not be able to call back home.

      The same thing will happen in those areas with spotty or weak signal network coverage - the battery will drain very fast. It is always a good idea to have an extra battery with you when you travel abroad.
