42. OneSimCard General Service Questions
    • Can I use a OneSimCard enabled phone in Japan, South Korea and Myanmar?

      All OneSimCard international SIM cards work in Australia, Japan, South Korea, Myanmar, Singapore and other couuntries where 2G networks no longer available. These countries use 3G/WCDMA networks, so only phones with the specific 3G/WCDMA/HSDPA/UMTS 2100 frequency will work in these countries. Most modern smart phones have this option today including all iPhones. You should check your phone specification to make sure your phone has this 3G band,

      OneSimCard offers cell phones with the necessary 3G band for Japan and South Korea that also work in every other country where we provide service:

47. OneSim VoIP
    • How does OneSim VoIP work when the call is received?

      When someone dials your OneSim VoIP enabled Personal Extra Number (PEN), the system will first check if your OneSimCard phone is registered with the OneSim VoIP app on a Wi-Fi network. If it is registered, the call will be sent using VoIP. If the OneSim VoIP app is not running or it is not registered on a Wi-Fi network, then the call will be sent using the standard OneSimCard roaming network and charged our standard roaming rates.
48. How To Use Questions
    • How do I set up SMS text messaging on my phone?

      SMS messaging usually works without any additional setup of the phone.
      In rare cases when there are issues sending or receiving text messages, please look at the following:

      Problem with Sending SMS:

      • Incorrect SMSC number (SMS Service Center Address) in handset settings.

      SMSC number should be set as follows:

       

      1. For Standard  and Plus OneSimCard SIM: +3725099000 for all countries except:

      a. China:  +85290296747

       

      2. For the Expedition (former Data & Roam) SIM as well as for Europe & More SIM: +37256100041

       

      Special instructions for Apple Phones:

      With Apple iPhones to check SMSC:

      From the phone dialer Dial *#5005*7672# 

      You will see the SMSC set currently on the phone. 

      To change the SMSC on Iphone dial: 

      Plus and Standard SIMs: **5005*7672*+3725099000# for all countries except China and **5005*7672*+85290296747# if in China.

      Expedition (formerly Data & Roam) and Europe & More SIMs in any country: **5005*7672*+37256100041#


       

       

      If your phone requires the name of Message Center Name enter: SMSC
      SMS lifetime is short - must be at least 2 hours or set to Maximum settings.
      Try sending SMS from OneSimCard menu

       

       Problem with Receiving SMS:

      • Receiving Handset does not have enough free memory for incoming SMS.
      • Receiving Handset was turned off or out of the coverage area during SMS lifetime set on the sending phone - usually 2 hours.
      • Sender's SMS provider does not have an agreement with the receiving network.
49. 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.
50. How To Use Questions
    • Is there a mobile app that will let me recharge my account and other services?

      Yes! Our myOneSim app for the iPhone devices will let you easily access many account services, such as recharging your account, checking voicemail, ordering discount voice and text plans, and much more. MyOneSim is available for download from the App store. Find more information in the Help section of your online account.
