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 Universal and Expedition 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. For eSIM World and DataMax eSIM, you can order Personal Extra Numbers (PENs) as needed for an additional cost.
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:Â 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.
You can forward your calls to your 1SIM VoIP PEN. Simply forward all calls from your phone number to your 1SIM VoIP PEN using the directions below. Normal charges will apply for receiving calls to your 1SIM VoIP number (there will be NO extra $0.20, or $0.25 for UK PEN, cost to receive a call on OneSim VoIP).
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 wireless carrier for assistance if needed.

Are there any discount call (voice) plans available for Europe or other countries?
Yes, discount calling plans are available on select sim cards.
"Discount A" Voice Calls Plan
You can subscribe to the Discount Call Plan A for Europe (see country list below) and Turkey for just $3.99! Subscription is good for 30 days and will not automatically renew. This plan is available on the Plus and Universal SIM cards.
Once the discount plan is activated, you will be able to make calls from the countries below for only $0.15/min starting with the second minute! The first minute will be charged at the regular outgoing call rate:

PLEASE NOTE: If you activate the discount A call plan, the special rate to make OneSimCard-to-OneSimCard calls and to call the voicemail system will not be available.

NOTE: There are no discount plans available on OneSIM VoIP. Because the cost of OneSIM VoIP is so deeply discounted, there are no packages available for voice on OneSIM VoIP.
Can eSIM be used for Data, Calls and Texts?
Yes, as of March 3rd, 2020, OneSimCard eSIM can be used for Mobile Data, Voice and Texts. However, you can still use the OneSim VOIP app option with a Personal Extra Number (PEN) for additional savings on calling and texting
Â
For DataMax eSIMs, only Data is available. However, you can use our OneSim VoIP app for cost effective voice and SMS communication.
How does eSIM works?
When I dial following your instructions it does not work. What's wrong?
This answer applies to SIM cards purchased before January 1, 2017.
Some phones, such as Samsung, some Motorola, Android and Apple iPhones, require special dialing instructions or simple OneSimCard settings menu changes in order to make calls.
It is possible to make almost any phone entirely compatible, so you can call directly without using the OneSimCard menu or *146* by following these simple programming instructions below.
How to activate compatibility mode:
 1. Locate OneSimCard Menu.
 On iPhones it is called SIM Applications menu and is located under Settings- Phone menu
     On Androids it is called SIM Toolkit app or OneSimCard app and it looks like one of the apps.
 Â
Bear in mind that if you have powered your telephone down, and have removed and reinstalled the battery, you will need to follow the programming steps outlined above, again.
If for any reason after entering compatibility code, you still do not get a ringback or you get the ringback the first time you make a call, but second time it would not work, please enter code 802 into the Service Code window instead of 1101 as provided above.
Â
iPhone users can download OneSimCard Assist App from iTunes that will takes care of the iphones compatibility issues, except for removing the ringback.
For example, calling to USA:Â Dial *146*0016175551212# and press the TALK (or SEND) button
The sequence *146* and # at the end can be used from any phone. However, most phones do not require it.
We strongly recommend you to watch very short video tutorials that will help you to understand how to make calls, SMS and data on your OneSimCard Phone.

Â
I just activated my SIM card and can't make a successful test call. What's wrong?
If you just activated your SIM card and can not make a test call by following the instructions in the user manual, you will likely just need to power off the phone and power it back on again. The phone should automatically re-register with one of our partner networks. Remember, if you answer the test call when it rings you will be charged for the call.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.I have an Apple iPhone. When I dial following your instructions it does not work. What's wrong?
 1. Locate OneSimCard Menu.
 On iPhones it is called SIM Applications menu and is located under Settings- Phone menu
Bear in mind that if you have powered your telephone down, and have removed and reinstalled the battery, you will need to follow the programming steps outlined above, again.
