Why do some SMS recipients see a Sender ID that is not my Salesmate number?

Sender ID change may occur when you send messages from a number that is not local to your recipients, for example- using a US number to send SMS to German mobile users. This is often done to comply with local regulations, or to ensure the highest possible delivery rate for your messages.

Sender ID change will not occur when you send messages using a number from the same country as the recipient, for example- using a German number to send SMS to a German mobile user.

Sender ID change does not negatively affect delivery quality, however it means that replies from recipients will not be routed back to your number.
