21. How To Use Questions
    • Can I use a OneSimCard phone to send an SMS message?

      Of course you can! Simply send and receive SMS texts according to your phone's user manual or from the OneSimCard Menu. Receiving SMS is always free. Sending an SMS (text message) is $0.15 - $1.50 depending on the country.

      SMS messages sent to a OneSimCard phone should always be sent to the main OneSimCard mobile number rather than to an optional Extra Number, with the exception of new SMS enabled numbers in USA, Canada and UK Mobile available since Jun 3rd, 2014. When replying from OneSimCard phone to the SMS received on USA or Canada SMS capable PEN using Europe & More sim or the Expedition SIM, the main number of the SIM that starts with 372 will be displayed on the text receiver phone. With the Universal SIM, you can select what caller ID will be shown on the SMS receiving party phone.

      You can also send SMS messages from OneSim VOIP app at much lower rates.


      You can also send a free SMS message to any OneSimCard customer from our web site or by sending email to 372XXXXXXXX@sms.onesimcard.com, where 372XXXXXXXX is the OneSimCard primary mobile phone number. The maximum number of daily SMS sent to the SIM over email or web is 25.

      Please bear in mind that message should be sent in English characters. In addition, it should not be longer than 160 characters including spaces.


      These 2 options of sending SMS by email provide completely free way of communicating, as it is usually free for you to send the email and costs nothing for the OneSimCard customer to receive a text message.

22. Troubleshooting Questions
    • I have an iPhone and am receiving charges for SMS sent to a UK mobile number 447786205094. Why?

      This is a known issue with Apple's Facetime and iMessage applications on Apple iPhone  devices. We recommend disabling Facetime and iMessage so it will not be able to automatically send SMS to this 447786205094 number. Any SMS sent to this number automatically by your phone can not be refunded by OneSimCard. Additional questions regarding iPhone applications and how they communicate should be directed to Apple Support.

    • Will¬†a OneSimCard international SIM card work with my mobile phone?

      OneSimCard will work with almost any unlocked GSM tri-band or quad-band cell phone. A partial list of compatible cell phones that we have tested can be viewed here.

      If you need to unlock the phone, we suggest contacting your carrier or phone manufacturer for unlocking information or services.

      If your phone is not a quad-band phone, please make sure that the bands of your phone are those required in the country of your travel. You can look it up here.

      OneSim VoiP can be used from any Android or Apple ( iOS) device to make international LD calls even when you are not traveling.

You just need to have OneSimCard account with the SIM VoIP capable PEN. Calling using OneSim VoIP will cost most of the time less than any other way of calling.
