Send and receive SMS messages with Uniden Voice — conversations are grouped like on your mobile and can be viewed across multiple devices.
There are two ways to SMS: one-way (send only, using a Sender ID name) and two-way (send and receive, using a mobile number on your account).
| Item | Detail |
|---|---|
| Outbound SMS | $0.10 per SMS |
| Inbound SMS | No charge |
| Mobile number (for two-way SMS) | $10.00 per month per number |
| Message length | 160 characters per SMS, or 70 if the message uses special characters |
Longer messages are split into multiple SMS parts, and each part is charged at $0.10. Using special characters lowers the per-part limit from 160 to 70 characters.
One-way SMS is available to everyone, even without a mobile number on your account. It sends a no-reply SMS showing a custom display name — for example, your business name. Recipients see your name but cannot reply.
You need an approved Sender ID before you can send.




Two-way SMS requires a mobile number on your account. Mobile numbers cost $10.00 per month per number and are added on the Numbers page — the same number can also make and receive calls.
Once a mobile number is applied to your account, it appears in the dropdown menu when you start a new SMS. If you have multiple mobile numbers, they all appear here.

SMS can also be sent and received through the VocPhone mobile app — only if you have a mobile number on your account. You can add several extensions/users to the one mobile number and view the SMS conversations on each of those devices. You can also set up email notifications here, which send a snippet of the SMS conversation to your email.


A Sender ID name lets you send SMS without displaying a mobile number as the sender — the recipient sees a name instead, usually your company name or brand.
Use a Sender ID name when:
This is particularly useful for marketing, notifications, and transactional messages where brand recognition matters.



If you do not already have a Sender ID name:
The following are not allowed as Sender ID names:
- Phone or mobile numbers.
- The name of a person not associated with the account.
- The name of a company not related to the account.
