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. Note: for Physical 3-in-1 Datamax and Damax eSIM all SMS messages MUST be sent through the OneSim VoIP App with PEN.
You can also send a free SMS message to any OneSimCard customer from our web site or by sending email to [email protected], 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.
How do I make a call using OneSimCard global cell phone service?
