For iD Mobile customers
Missed call text service for iD Mobile
iD Mobile is a low-cost SIM-only network that is popular with sole traders watching every overhead. It handles calls and texts perfectly well — but like every network, it sends unanswered calls to voicemail, and your customers will not leave one. TextTheCaller turns those unanswered calls into a text from your business name so the caller has a reason to wait for you.
iD Mobile runs on the Three network
iD Mobile is owned by Currys and runs on Three's network. iD confirms that call forwarding to standard UK voice numbers is supported, and it is configured from your handset's call forwarding screen. One thing worth checking before you leave it running permanently: depending on your tariff, forwarded calls may use inclusive minutes or fall back to standard rates, so it is worth confirming which applies to your plan.
Worth knowing: iD Mobile 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 iD Mobile
iD Mobile confirms call forwarding can be used to standard UK voice numbers. Configure it from the handset call forwarding screen.
-
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.
Forwarded calls can use inclusive minutes or fall back to standard rates depending on the tariff, so verify that before leaving it on permanently.
iD Mobile's own documentation: iD Mobile help
What your iD Mobile 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 iD Mobile: common questions
Yes. iD Mobile supports call forwarding to standard UK voice numbers, which is what this service uses.
It may, depending on your tariff — some plans include forwarded calls in your allowance and others charge standard rates. Check your plan details. The forwarded leg is momentary because we reject the call rather than answering it.
On the handset, in your phone's call forwarding settings — not in the iD Mobile app. Use the unanswered or "no answer" rule only.
