For SMARTY customers
Missed call text service for SMARTY
SMARTY appeals to exactly the kind of business that loses the most from a missed call: lean, SIM-only, no contract, running the whole operation off one mobile. If that is you, every unanswered call is a job going to whoever the customer rings next. TextTheCaller makes sure they hear from you first, by text, within seconds.
SMARTY runs on the Three network
SMARTY is owned by Three and runs on Three's network, so unanswered-call forwarding is available as a standard network feature. SMARTY documents both the handset menu route and forwarding shortcodes. The handset menu is the safer option for most people because it is harder to enable the wrong rule by mistake, but if you are comfortable with keypad codes, SMARTY's own help page covers them.
Worth knowing: SMARTY is a virtual network that runs on Three's infrastructure, so unanswered-call forwarding behaves the same way it does on a direct Three line.
Setup
Setting it up on SMARTY
SMARTY publishes help for call forwarding and missed-call diversion. The handset menu is still the safest setup path for most users.
-
1
Open the Phone app or your handset settings and find Call forwarding or Call divert.
-
2
Choose the rule for When unanswered or No answer only. Do not turn on Always forward.
-
3
Enter your TextTheCaller forwarding number. You get it the moment you sign up, together with the exact dial code for your network.
-
4
If your phone asks for a delay before forwarding, use 20 seconds.
-
5
Save the change and place a quick test call from another number.
You'll get the exact forwarding number and the dial code for your line when you sign up — the placeholders above are filled in for you.
SMARTY also documents forwarding shortcodes. Use the official help page below if you prefer keypad codes over the menu flow.

What your SMARTY caller receives
An SMS from your business name — not a number they don't recognise — with whatever message you've written, delivered within seconds of the call going unanswered. We never answer the call itself: your network forwards it to us, we reject it immediately, and the text goes out. There is no receptionist, phone menu or hold music between you and your customer.
Because it sends from your business name rather than a phone number, the message is one-way — the caller can't reply to it. That's why a good text-back gives them something they can act on instead: a booking link, an email address, or simply when you'll ring them back.
Mobile numbers only
Landlines, withheld and international callers are skipped, so you never burn a text on a number that can't receive one.
One text per caller
The same person calling repeatedly gets one message every 7 days, not one per call.
50 texts a month
Included in the £6.49/month price. No per-text charges and no surprise bills.
Missed call texts on SMARTY: common questions
The handset menu, unless you are confident with keypad codes. The risk with codes is enabling unconditional forwarding by accident, which would divert calls you would otherwise have answered.
The forwarded leg is treated like an outbound call and may draw on your plan allowance. Since we reject the call on arrival rather than answering it, that leg is momentary.
Yes. Unanswered-call forwarding is a network feature and does not depend on which SMARTY plan you are on.
