41. OneSim VoIP
    • Do I need to have a OneSimCard SIM card installed in my phone to use OneSim VoIP?

      No. OneSimCard SIM is not required to be installed in the phone for OneSim VoIP to be used. However, you do need to have OneSimCard account with a VoIP capable PEN.
42. 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.
43. OneSim VoIP
    • How does OneSim VoIP work when the call is received?

      When someone dials your OneSim VoIP enabled Personal Extra Number (PEN), the system will first check if your OneSimCard phone is registered with the OneSim VoIP app on a Wi-Fi network. If it is registered, the call will be sent using VoIP. If the OneSim VoIP app is not running or it is not registered on a Wi-Fi network, then the call will be sent using the standard OneSimCard roaming network and charged our standard roaming rates.
44. How To Use Questions
    • Can I be notified of missed calls when my phone is off or outside of a coverage area?

      Yes, for Universal, Expedition, and eSIM World Sim Cards, you will receive SMS or email notifications when you miss a call due to your phone being off or out of coverage. SMS notifications are sent when the phone is unavailable for a period up to 4 hours. Email notifications are sent, regardless of the time period, to the email address you have entered into your online voicemail profile. Notifications will be sent when you make/receive a call or enter a new roaming country. NOTE: if the caller leaves a voicemail message then you will not receive this extra missed call notification.
45. Troubleshooting Questions
    • I have a OneSimCard SIM and my phone will not register on a roaming network, what's wrong?

      Sometimes when moving from the USA, Canada or Mexico to another country, the SIM card will need to be reset to properly register on a new country roaming network.

      • If you have the OneSimCard Menu on your phone (it may be called Sim Application Menu on iPhones or SIM Toolkit on Androids), go to the menu, scroll down to Settings and enter Service Code 2003 and confirm, then Code 000 and confirm. For older SIM cards after this enter Service Code 1101 and confirm. Turn the phone off and then back on. 

      • If you do not have access to the OneSimCard Menu then turn off your phone, remove the battery for 20 seconds, reinstall the battery and then turn back on your phone.
46. Troubleshooting Questions
    • Does iPhone Hotspot work with OneSimCard?

      Yes. All unlocked iPhones' Hotspot feature works with OneSimCard SIM.

       
      There are a few settings to make sure for this to function properly on your iPhone:
      1. Settings - Cellular - Cellular Data - ON
      2. Settings - Cellular - Data Roaming - ON
      3. Settings - Cellular - Cellular Data Network - Cellular Data - APN = APN will be set automatically
      4. Settings - Wi-Fi - ON
      5. Settings - Personal Hotspot - ON. 
      After turning the Hotspot on, you should stay on the Personal Hotspot screen of your iPhone for SSID of your phone to show up on other Wi-Fi devices, so you can get connected. After you connected to the Hotspot, you can leave the screen. Alternatively, you can always use Bluetooth or USB connection to provide the internet access from your OneSimCard iPhone Hotspot to your other devices.

48. How To Use Questions
    • How do I prevent the service from expiring?

      The OneSimCard phone number has no expiration, provided you made at least 1 call or sent an SMS once every 12 months.

      However, the funds on the SIM expire 10 months after your last recharge. The minimum recharge amount is $25. You can keep the balance from expiring by simply recharging at least once every 10 months. If you let your balance expire, then all you need to do to get the service up and running again is to log in and add funds to your SIM card. Automatic recharge will be canceled if you let your funds expire.

      NOTE: For Physical 3-in-1 DataMax & DataMax eSIM SIM cards, if the SIM card has no balance, the SIM will expire and be removed from the account after 7 days, unless there is a data package currently active on the SIM (not a future activation). If there is no balance on the SIM and the active data package expires, the SIM will expire 7 days following the expiration of the active data package.

       

      An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.
