How do I divert calls on Three?
Three doesn't publish divert codes, so use your phone's settings. On Android, open the Phone app, then Settings, then Call forwarding. On an iPhone, ask Three by calling 333 from your Three phone. Three's Advanced Plans price guide says each diverted call is charged, depending on the number type.
Three doesn't publish divert codes on its own pages, so we don't list any here.
What should I check before I start?
- What it costs: Three's price guide for Advanced Plans says "If you divert your incoming calls to another number, we'll charge you for each redirected call. The cost of the redirected call depends on the type of number." Check the price guide for your own plan.
How do I set up a divert on Three?
On an Android phone
- Open the Phone app.
- Tap the menu (three dots), then Settings or Call settings.
- Tap Call forwarding.
- Set each of the three diverts (when busy, when unanswered, when unreachable) to your Hold The Fort number.
Menu names vary by phone.
On an iPhone The iPhone's Call Forwarding setting sends every call on, so your phone won't ring. To divert only the calls you miss, ask Three.
Ask Three Call 333 from your Three phone, or 0333 338 1001 from any other phone.
