What are my purchase options?

Our SMS marketing service offers both a Monthly Messaging plan and a Pay as You Go Messaging plan and you are never charged for any failed messages. Monthly Messaging plan messages expire 30 days after the initial date of purchase and do not roll over towards the next month. Monthly plans are automatically renewed and charged to the credit card on file every 30 days until notification of cancellation.

Additionally, a one time $15 vetting fee and a $12 monthly fee will be imposed for the phone number linked to your account.

What is the $12 monthly fee for?

The $12 monthly charge goes towards covering the cost of the phone number and the registration required for each phone number. MobileSphere, like other carriers, is now required to register each number on behalf of its customers with The Campaign Registry (TCR).

TCR works with North American mobile operators and companies that are in the messaging business to register text messaging Campaigns. The registry supports a sanctioned A2P 10 Digit Long Code (10DLC) text messaging Campaign ecosystem and provides visibility into the messaging source and content, allowing mobile carriers to provide a more reliable and predictable messaging service for Campaign Service Providers (CSPs) and Brands.

Do my messages ever expire?

All Pay as You Go plan messages do not expire. Monthly Messaging plan messages are valid for 30 calendar days after your initial date of purchase and do not roll over towards the next month.

How many messages can I send out per day with slyText?

Carriers impose certain restrictions on the number of text messages that can be sent per hour and per day. The daily limit is 3,000 text messages per day and are sent out at a rate of 140 text messages per minute. Contact us for more information.

Will I receive notifications of unread messages?

Within your slyText account, you can choose to enable browser notifications and/or SMS forwarding. To receive browser notifications, your slyText account page must remain open.

By enabling SMS forwarding, you will receive all incoming messages to the registered phone number we have on file. Forwarded messages cost one credit per message forwarded. To reply to the message, you must log in to your account. Carrier rates apply.

Can I send a slyText message from my own phone number?

Yes. We can text enable your own landline or VoIP number or you choose a slyText phone number from within your preferred area code. Your messages will be sent from this number and recipients are able to reply to it directly. All slyText messages will come from a 10-digit phone number. Short codes are never used. To text enable your own landline or VoIP number, contact us at

How am I charged with slyText?

With slyText, you are charged for outgoing, incoming and any messages that are SMS forwarded to your registered phone number.

If a phone number fails to receive a text message, you are still charged as we are charged every time we pass your message through our SMS gateway.

A text of 160 characters or less equals one (1) message. An MMS message (audio, video or text) equals three (3) messages.

Does slyText work with international numbers?

SlyText web texts can only be sent to U.S. and Canadian mobile phone numbers. However, we are working hard to expand this to as many countries as we can.

Does slyText work with all mobile providers?

Yes. SlyText works to all major U.S. and Canadian wireless providers so your customers can receive text messages to their mobile devices wherever they happen to be.

What charges, if any, will my carrier charge me for using slyText?

You will not incur any charges from your wireless carrier for sending out or receiving text messages using slyText. However, if you turn SMS forwarding on, (so that you receive responses on your mobile phone in addition to the slyText website), your carrier will charge you what they normally do when you receive a text message on your mobile phone.

Will the person receiving my text messages be charged?

Yes, the person you send a text message to will be charged by their carrier as they normally would for receiving a text message. For carriers, a slyText text message is no different than receiving a text message directly from your mobile phone. So, depending on what type of text messaging plan they have, they will be charged accordingly.
