    • Can I forward calls from my OneSimCard phone to another number?

      Yes. Your OneSimCard mobile number can currently be forwarded to EU, Canada, USA, Russia, Ukraine and Belarus numbers. It's 100% free to forward your OneSimCard phone number to many countries including to U.S. or Canadian numbers. Forwarding to some countries, as well as to satellite phones, will carry a forwarding charge as listed in the Rates & Coverage page on OneSimCard.com.

      To enable/disable call forwarding from your online account:

      Log in at OneSimCard.com and go to the My SIM Cards menu. Select your SIM card number and enable/disable Call Forwarding on this screen.

      To enable/disable call forwarding from your phone:

      Dial *146*081*XXXXXXXXXXXXX# and press Send/Talk (where XXXXXXXXXXXXX is the forward-to number in international format: 00+countrycode+number)

      Newer SIM cards use *81* instead of *081*

      Example: to forward to U.S. number 1-617-555-1212, dial *146*081*0016175551212# and press Send/Talk.

      If you get an "Unknown Format?" message, dial *146*81*0016175551212#

      To disable call forwarding, dial *146*080# and press Send/Talk. If you get an "Unknown Format?" message dial *146*80# and press Send/Talk.

    • Can I browse the Internet and check email, use Whatsup and Facebook from my OneSimCard phone?

      Yes, you can browse the Internet, check email and use other data services with OneSimCard. Service is available in over 100 countries. Please check the OneSimCard Rates Page to see if GPRS internet access is available in your country of interest. Note: data is charged in 10kB increments.

      By default, all SIM cards are pre-programmed with GPRS data service disabled. To enable GPRS and find the programming instructions for your phone, log in to your OneSimCard account, click the "Enable" link for Mobile Internet and then click on Remote Program. Programming your mobile phone is very simple and can be done remotely by sending the programming instructions from OneSimCard.com to your phone. Not all phones are capable of being programmed remotely, so please review the data programming instructions located in the OneSimCard User Guide and in the Help section of your online account.

      Please note: you must have a minimum $5 airtime on your SIM card to use GPRS mobile data service.
44. OneSimCard General Service Questions
    • I have an Verizon or Sprint Smart Phone ( iPhone, Samsung Galaxy, 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.

    • Can I send SMS text messages to a OneSimCard enabled phone by email?

      Yes, you can send SMS messages by sending an email to 372XXXXXXXX@sms.onesimcard.com, where 372XXXXXXXX is the 11-digit OneSimCard mobile phone number you are trying to reach.

      Please note that message should be sent in English characters only and no attachments to this email are allowed.

      This option of sending SMS by email provides a completely free way of communicating, as it is usually free for you to send the email and costs nothing for the OneSimCard customer to receive it. The maximum number of daily received SMS sent by email or from the web per SIM is 25.

       

      Starting June 3rd, 2014 OneSimCard offers new USA and Canada PENs capable of receiving SMS ( Text Messages) . These PENs carry a charge of 9 cent per received SMS. These PENs can receive only SMS sent from a mobile device and will not receive texts sent from web sites of Gmail, Yahoo, banks etc. If you need to receive alerts from the web site sent to your mobile phone, we suggest you to select the alert option by email and provide OneSimCard email of your phone 372XXXXXXXX@sms.onesimcard.com, which you will receive as an SMS.

       

      Starting January 10th, 2019 OneSimCard offers new UK Mobile PENs capable of receiving SMS and sending SMS. Receiving text on UK Mobile SMS number is free.

46. 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.

    • Can I keep receiving calls made to my regular cell phone or landline numbers while traveling abroad?

      Yes, you can easily forward calls from your regular cell phone number, home phone, office, etc. to your OneSimCard phone while you're abroad!

      Your OneSimCard international SIM card comes with both a European and U.S. number. To forward your regular U.S. numbers to the SIM, just set them to forward to the U.S. number that's included with your SIM card.

      You can also order unlimited Personal Extra Numbers (PEN) - Local or Toll Free - in many different countries, including USA, Canada, UK, France, Italy and Spain. For example, if you work or live in the UK and want to keep receiving calls made to your regular UK numbers, just add a UK PEN to your SIM card and set up call forwarding to that new number.

      Calls received through a PEN will be charged an additional 20c/min to the incoming rate of the country you are in. The exception is calls received through a UK-Mobile PEN which is only charged an additional 25c per call.

      Please Note: Your subscription to a Personal Extra Number starts the moment your order is shipped. If you do not need your PEN to be active right away, you can always wait and order a PEN later at any time by logging in to your account.

      Different carriers use different ways of programming call forwarding. Below are instructions to setup call forwarding with various US wireless carriers. We urge you to test the call forwarding a few days prior to your trip, and to call your US wireless carrier for assistance if needed.

49. 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.

       

       

50. OneSimCard General Service Questions
    • What is the difference between eSIM, OneSimCard Universal, OneSimCard Expedition (formerly Data & Roam) and OneSimCard Europe & More SIM cards?

      All 4 OneSimCard SIMs work in a very similar manner.  They all use an Estonian Mobile Number as the primary number and offer a Free US or Canada PEN for 30 days. All OneSimCards also offer many  additional features such as Live Customer Support, SIM VOIP and Apps for iPhone and Android.

      The main difference between the 4 SIM cards is that OneSimCard Universal and eSIM offers Voice and SMS Text Messaging in many more countries as well as lower data rates.  The OneSimCard Expedition (formerly Data & Roam) is recommended to be used in some countries where for it offers coverage while Universal SIM does not.  For some countries like Canada, Cuba, Brazil and a few others, the OneSimCard Expedition (formerly Data & Roam) offers lower calling rates. 

      The OneSimCard Europe & More was specially created for European travelers and offers our best calling rates to the US & Canada from the 40 included countries. Both the Europe, eSIM and Universal SIM cards offer easy Direct Dialing in 40 (EM) and 75 countries respectively, while OneSimCard Expedition (formerly Data & Roam) utilizes callback. eSIM and Universal SIM offers callback dialing in those 130 countries which are not covered by the Direct Dialing. Callback dialing does not make it more complex for the caller, except for pressing the Talk button on the mobile phone twice instead of once when making a call.

      OneSimCard Universal, Plus, OneSimCard Expedition (formerly Data & Roam) and OneSimCard Europe & More also operate on different networks in many countries.

      You can compare rates for all these SIM cards here.
