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

      Yes. Your OneSimCard mobile number can be forwarded to almost any other number around the world! 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. There are a few exceptions where calls can not be forwarded to certain numbers.

      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 "Unkown 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.

65. OneSimCard General Service Questions
    • Do I need to activate the SIM card when my order is received or purchased from a retail store?

      Yes, you will need to activate the SIM card once the order is received.

      All OneSimCard international SIM cards and international cell phones with SIM cards are shipped inactive to prevent theft and improve security. Only the person who placed the order for OneSimCard service can activate it.

      Activation is very simple: When you receive the SIM, just log in to your account at www.OneSimCard.com and click the large Activate button you will see in the middle of the screen.

      Retail Customers: If you purchased your SIM card through an online or brick-and-mortar retail store, you should have received activation instructions inside the product packaging. To activate retail SIM cards, go to www.OneSimCard.com/Retail enter your new OneSimCard international mobile number and fill out the form to register and activate the SIM card.
66. 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.

67. OneSimCard General Service Questions

      New Toll Free access number for customers in the U.S. or Canada to retrieve voicemail for free: 1-866-703-4770

      New local U.S. number for worldwide customers to retrieve voicemail: 1-213-805-2905

68. 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. 
69. OneSimCard General Service Questions
    • What is the difference between OneSimCard Universal, OneSimCard Expedition (formerly Data & Roam) and OneSimCard Europe & More SIM cards?

      All 3 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 Global Concierge, 24/7 Live Technical Support, SIM VOIP and Apps for iPhone and Android.

      The main difference between the 3 SIM cards is that OneSimCard Universal 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 and Universal SIM cards offer easy Direct Dialing in 40 and 75 countries respectively, while OneSimCard Expedition (formerly Data & Roam) utilizes callback. 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.
