Sender ID

Due to the architecture of the API, anti-spam regulations and to improve your delivery rate we deliver all your sent messages with your SMS number as Sender ID.

Please always keep in mind, that carrier of the receiver has the power to replace it with some other Sender ID.

Some information we feel will be useful for you:
—  What is the message length?
—  Can I send and receive messages with Unicode?
—  I do not receive messages sometimes
—  Sent messages are not delivered sometimes
—  Formatting international phone numbers
—  Sender ID
—  Spam
