When you buy an Exophone, you will be asked to enter a 6-letter sender ID from which your SMSes will be sent. For Eg: LM-EXOTEL or LM-HDFCBK etc.
Let's say for some reason your entered a sender ID while getting a new ExoPhone number and now you want to change it. Here's what you need to do:
2) Click on the 'Edit' button next to the sender ID. Remember every number can have it's own sender ID. As highlighted in the image below :
3) Enter a 6 letter sender ID in upper case. No numbers or special characters. Only letters of the english alphabet. Also, the sender id needs to be exactly 6 letters long. For eg: EXTEL or MYSTR are not allowed.
4) Click 'OK' and then Sit back and wait
We will typically approve the sender ID within 1 working day after which the new sender ID will be reflected in that page. You will also receive a confirmation mail regarding this. Till then your old sender ID will still be in use.
