41. OneSim VoIP

    • Do I need to have a OneSimCard SIM card installed in my phone to use OneSim VoIP?

      No. OneSimCard SIM is not required to be installed in the phone for OneSim VoIP to be used. However, you do need to have OneSimCard account with a VoIP capable PEN.
42. OneSim VoIP

    • When I make a call using OneSim VoIP the quality of the call is not as good as the quality of the regular roaming connection. Can this be improved?

      The quality of a OneSim VoIP call is only defined by the quality of your Wi-Fi connection. This is the part of the connection that we can not control. Quality of the Wi-Fi connection is defined by many parameters, rather than just by the speed of the connection. With a good Wi-Fi connection the quality of the call will be similar to using our regular roaming network.
43. 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.
44. How To Use Questions

    • Can I use OneSimCard data (GPRS) service on my BlackBerry?

      Yes! We do offer data (GPRS) service on BlackBerry devices from models 8000 and up. This is separate from BlackBerry Internet Service (BIS) & Blackberry Enterprise Server (BES). Emails can not be pushed to the phone and BlackBerry Web Applications and Messenger will not work. However, access to web-based emails like Gmail and Yahoo as well as Internet browsing will work.
45. 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 SIM that does not use the callback to make a call, you will just get connected.

      With OneSimCard Plus SIM or Expedition (formerly Data & Roam) SIM:

      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.
