1. 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.

2. OneSimCard General Service Questions
    • What Is the Difference Between "Direct Dial" and "Callback Dial" calling?

      Direct Dial calling allows the caller to enter the international  call prefix, country calling code and telephone number and then be directly connected to the person they are calling. This is how you dial when using your regular mobile service. Direct Dial Calling is standard on the OneSimCard Europe & More, OneSimCard Universal and eSIM.

      Callback calling also allows the caller to enter the international  call prefix, country calling code and telephone number. After the called number is entered, the user immediately receives an incoming call connecting the user to person called. Callback is very simple to use and allows for low cost calling on the OneSimCard Plus and OneSimCard Expedition (formerly Data & Roam). Callback does not increase the connection time. It is the same as with Direct Dial.

3. 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.

4. Rates and Cost Questions
    • Is there a monthly or 30-day credit card spending limit for OneSimCard service?

      To reduce fraud, there is 30-day credit card spending limit set for each individual account. You will only be able to charge up to a certain amount during any 30-day period. You can see your current limit by logging in to your OneSimCard account and going to the Purchase History menu. There, you will find a Credit Card Authorization form available for download. If you would like to increase your monthly credit card spending limit, please download the Authorization form and submit it back to OneSimCard as instructed on the form.

      We strongly suggest that you set your monthly credit card limit before going overseas as dealing with the form on the road can be much more difficult.
5. OneSimCard General Service Questions
    • Will I get a bill for using OneSimCard service?

      No. OneSimCard service is a prepaid service. You will not be able to spend more than you put on the SIM, except when you set the automatic recharge of the SIM. There are three simple ways to add funds to the balance of the SIM: from on-line, from the mobile phone and by setting up an automatic recharge. This pertains to both - purchased SIM cards and rentals.

8. OneSimCard General Service Questions
    • Can I move Personal Extra Numbers (PENs) between SIM cards in my account?

      Yes, you can move PENs within both private and corporate accounts. There is a small fee per PEN transfer which will be deducted from the SIM card the PEN is being moved to. If there is not enough money on this SIM, the fee will be deducted from the SIM the PEN is being moved from. If neither SIM card has enough balance, you’ll have an option to recharge. Transaction records will be posted under the History menu.

9. 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.
