61. Rates and Cost Questions
    • Does calling a mobile phone cost more than calling a landline?

      It does not cost more to dial an international mobile number using OneSimCard service on traditional cellular connections. You will receive the same very low per minute rate whether calling to a mobile phone or to a land line. 

       

      For OneSim VoIP, the cost of calling Mobile numbers is typically higher than calling landlines, but this method is still less than traditional voice calls in most countries..


      You can find all rates listed on our Rates & Coverage page.

62. How To Use Questions
    • Can I check my Voice Mail from a phone other than my OneSimCard phone?

      Yes. You can access the Voice Mail from other phones.

      First you need to set up a voicemail password by either calling from your OneSimCard phone or logging in to your account and clicking on the Voicemail link.

      Once the password is set up, you can dial voice mail access number:

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

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

      New Online Voicemail Feature: You can now listen to voicemail for free by logging in to your account and clicking on the Voicemail link. There, you can also set voicemail to be emailed to you as an audio file and change passwords and other settings.

      IMPORTANT NOTE: Voicemail messages will be automatically purged from your inbox after one month, so please be sure to save the content of any important messages before they are deleted.
      This does not apply to DataMax SIM cards
63. How To Use Questions
    • How do I make a call using OneSimCard global cell phone service?

      To make a call:

      • Dial 00-CountryCode-AreaCode-Number and press the TALK/SEND button.
        Example: To call OneSimCard Support in the USA you would dial 00 1 617 3138888 and press TALK/SEND. 

      With Europe & More, Univesal and eSIM World that do not use the callback to make a call, you will just get connected.
       
      With OneSimCard Plus SIM or Expedition (formerly Data & Roam) SIMs:

      After pressing the TALK/SEND button you will see a variable message on the screen (for example 'Wait for call') which you can ignore and your phone will ring back in a few seconds. Answer this ring as you normally would answer any incoming call. Your call will then be connected.

      If you are unsure about how to properly dial an international number, follow this link for detailed country by country dialing instructions.

      For Physical 3-in-1 DataMax, and DataMax eSIM cards, you can place calls using our low cost OneSIM VoIP service. OneSim VoIP costs much less than traditional voice roaming.

64. Troubleshooting Questions
    • Does iPhone Hotspot work with OneSimCard?

      Yes. All unlocked iPhones' Hotspot feature works with OneSimCard SIM.

       
      There are a few settings to make sure for this to function properly on your iPhone:
      1. Settings - Cellular - Cellular Data - ON
      2. Settings - Cellular - Data Roaming - ON
      3. Settings - Cellular - Cellular Data Network - Cellular Data - APN = APN will be set automatically
      4. Settings - Wi-Fi - ON
      5. Settings - Personal Hotspot - ON. 
      After turning the Hotspot on, you should stay on the Personal Hotspot screen of your iPhone for SSID of your phone to show up on other Wi-Fi devices, so you can get connected. After you connected to the Hotspot, you can leave the screen. Alternatively, you can always use Bluetooth or USB connection to provide the internet access from your OneSimCard iPhone Hotspot to your other devices.

69. Rates and Cost Questions
    • How often do I need to recharge my OneSimCard account?

      For Universal E, Expedition E, eSIM World E, eSIM Asiania, Plus, Europe & More, & Standard SIM Cards, the international SIM card phone number and account will expire if no outgoing usage is made for 12 months. The outgoing usage could be any of the following: Call made from the phone, SMS sent from the phone or any Data Usage.

      Personal Extra Numbers will stay active as long as they have been funded properly.

      The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10 month period provided that at least $25 is added within 10 months after the last recharge.

      If the balance expires, the service can still be used after a new recharge of the SIM card.

      For Physical 3-in-1 DataMax & DataMax eSIM SIM Cards, the SIM card and account will expire if no outgoing usage is made for 12 months. The outgoing usage could be any of the following: Call made from the OneSIM VoIP App, SMS sent from the OneSim VoIP app or any Data Usage.

      Personal Extra Numbers will stay active as long as they have been funded properly and the SIM hasn’t expired. If the SIM card expires, but then is restored ($10 Restoration Fee applies), the PEN will be re-attached to the SIM card, as long as the PEN hasn’t expired based on the time period for which the PEN was purchased.

      The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10-month period provided that at least $25 is added within 10 months after the last recharge.

      If the SIM card balance expires, the SIM will expire and be removed from the account after 7 days, unless there is a data package currently active on the SIM (not a future activation). If there is no balance on the SIM and the active data package expires, the SIM will expire 7 days following the expiration of the active data package. So, to keep the SIM active you need to either keep a balance on the SIM or an active data package. 

      NOTE: If there is balance on the SIM card, but no data is used for 15 consecutive days, the SIM card will be blocked/suspended. To unblock the SIM card, simply go to your account portal and in the "My SIM cards" tab, click on "Unblock" on the "SIM Type" line.

      An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.

       

70. How To Use Questions
    • How do I prevent the service from expiring?

      The OneSimCard phone number has no expiration, provided you made at least 1 call or sent an SMS once every 12 months.

      However, the funds on the SIM expire 10 months after your last recharge. The minimum recharge amount is $25. You can keep the balance from expiring by simply recharging at least once every 10 months. If you let your balance expire, then all you need to do to get the service up and running again is to log in and add funds to your SIM card. Automatic recharge will be canceled if you let your funds expire.

      NOTE: For Physical 3-in-1 DataMax & DataMax eSIM SIM cards, if the SIM card has no balance, the SIM will expire and be removed from the account after 7 days, unless there is a data package currently active on the SIM (not a future activation). If there is no balance on the SIM and the active data package expires, the SIM will expire 7 days following the expiration of the active data package.

       

      An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.
