Unfortunately, this cannot be done.
Global telco regulations and compliance are extremely complex. SMS messages are sent in Segments of 160 characters. For that reason, we limit the SMS body to 100 characters, and the remaining 60 characters are reserved for the link URL. If we send longer messages or multiple identical messages in a short time, there are very high chances we get blocked by the carrier.
We also do not recommend adding any URLs in the 100 characters (Eg. a bit.ly URL with instructions) or your SMS messages may get flagged. We have worked with operators to whitelist our name, numbers, and URLs and agreed to regulations that SMS will only be sent for Transactional purposes (Eg, OTP, or Code). This does not allow us to send informative content which may be marked as marketing.
