1. OneSimCard General Service Questions
    • Can I use OneSimCard service if my phone is locked?

      Yes. There are 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 OneSimCard  SIM 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.
2. OneSimCard General Service Questions
    • How do I know if my phone is locked or unlocked?

      To determine if your phone is locked, if you haven't already purchased a OneSimCard international SIM card then call your wireless provider. If you have already purchased from us then insert the OneSimCard SIM card. If you get any of the following messages on your screen after entering the pin then your phone is locked:

      • Insert SIM
      • SIM not valid
      • SIM Card Not Accepted
      • Enter Restriction Code
      • Enter Special Code
      • Enter Subsidy Code
      • Enter Subsidy Password
      • Contact Service Provider (Motorola)
      • or any other similar messages!

      Some mobile phone carriers lock their phones so they can't be used with other carriers. The simplest way to find out if the phone is locked is to borrow a SIM card from anybody who is using a different mobile service provider. If you power-up the phone and it recognizes the SIM card, your phone is unlocked and OneSimCard's international SIM card will work as well.

      If you need to unlock the phone, we suggest contacting your carrier or phone manufacturer for unlocking information or services.

      US Customers can read more about unlocking phones in this article of the Computer World magazine.

       

       

3. How To Use Questions
    • Can I be notified of missed calls when my phone is off or outside of a coverage area?

      Yes, 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.

    • What to do if I am unable to unlock my mobile phone?

5. Troubleshooting Questions
    • I have a Plus 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.
6. Troubleshooting Questions
    • What should I do if my OneSimCard phone or SIM card is lost or stolen?

      If your phone or SIM card is lost or stolen and automatic recharge is on, this could be a serious problem.

      To prevent this, log in to your account and activate the option to block your service immediately after you notice your phone or SIM card is missing. You can find this option in the My SIM Cards menu. Your OneSimCard service for this SIM card number will be instantly blocked. The remaining balance on your lost SIM can be transferred to another SIM card on your account or you can order a replacement SIM card if you would like to keep your phone numbers from the lost SIM.

      Alternatively, you can contact customer service online or call 001-617-313-8888 for assistance.

7. How To Use Questions
    • There is no OneSimCard Menu (SIM Toolkit) in my Android phone. How can I fix this?

      Some recent Android upgrades to versions 4.2.1 and 4.2.2 have a bug causing the OneSimCard Menu, labeled as SIM Toolkit, to be disabled.

      If you do not see the SIM Toolkit app in your Android phone, please try doing the following:

      Go to Settings>Security>Setup SIM Card Lock>Lock SIM Card. It will ask for the default SIM PIN. Enter 0000. Power off the phone and turn it back on. The SIM Toolkit app will then become available, though it might take 1-2 minutes for the phone to display it.

      On Android version 5.1 go to Settings > SIM Cards > SIM Toolkit

      Once you have access to the SIM Toolkit, select it, scroll down to Settings, enter 1101 and press confirm. Your phone will now be able to dial normally.

8. OneSimCard General Service Questions
    • I have an Verizon or Sprint Smart Phone ( iPhone 4S, Iphone 5, HTC, etc). Will OneSimCard work with my phone?

      Verizon and Sprint now offer dual mode - CDMA and GSM phones, which are capable of working on GSM networks. You can request Verizon and Sprint to unlock the GSM portion of the phone for international travel and they will most likely do this for you. However, Verizon and Sprint usually does not unlock phones 100% - they do this partially, so you are not able to use the phone while in USA.

      In such Verizon and Sprint phones you can get invalid message when inserting OneSimCard SIM or your phone does not find US networks. Verizon and Sprint unlock their phones in such a way that you can't use it in USA, but once you are out of the country the SIM will be accepted. Unfortunately, there is no way to tell the difference with this kind of unlocking if the phone is not unlocked or partially unlocked to work only outside of USA. In our experience, once this kind of phone leaves USA, it starts working.

9. OneSimCard General Service Questions
    • Will my CDMA cell phone from Verizon or Sprint work overseas with OneSimCard?

      No, unless you have a "World Phone" from Verizon or Sprint that is dual-mode CDMA/GSM. Most current smart phones including iPhones 4S, 5 and 6 offered by Verizon, Sprint, N-Telos and other CDMA carriers have GSM radio and will work when traveling abroad.

      CDMA-only phones will not work with OneSimCard service. OneSimCard service requires an unlocked GSM capable phone (for example, all AT&T or T-Mobile phones are GSM). Some domestic carriers such as Verizon and Sprint use CDMA technology, while most of the rest of the world uses GSM. Check with your wireless provider or phone manual if you are not sure if your phone is CDMA or GSM.

      Verizon and Sprint now offer iPhone 4S, 5 and 6, as well as some models of Samsung Galaxy phones which are capable of working on GSM networks. You can request Verizon and Sprint to unlock the GSM portion of the phone for international travel and most probably they will do this for you. Once they unlock the phone you can use OneSimCard SIM when traveling abroad. 
10. OneSimCard General Service Questions
    • Will a OneSimCard international SIM card work with my mobile phone?

      OneSimCard will work with almost any unlocked GSM tri-band or quad-band cell phone. A partial list of compatible cell phones that we have tested can be viewed here.

      If you need to unlock the phone, we suggest contacting your carrier or phone manufacturer for unlocking information or services.

      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.

      If you are still unsure whether your cell phone is compatible, contact support or purchase an international cell phone and SIM card bundle from us, which all come preloaded with our international SIM card, $10 balance and All in One International Travel Adapter Plug.
