Two phones, one number?

[Beefuhfulchi]

I've had a phone on contract for the past year and still have another year to go, but I also added an S24 ultra to my account, now I have two phones with active contracts. Is there any way to use the phone number from my original phone across both phones, so I don't have to keep checking both?

@Dougal62   What’s possible on other networks around the world doesn’t mean it’s possible on all networks.  No uk network supports this.

The technical specifications are global in nature, not country-specific.

There was a feature on Ericsson core networks called "Group Number" that allowed multiple SIM cards to have the same MSISDN. Vodafone did have this implemented but I believe pulled the capability some time ago. Its purpose for for businesses for example where several employees could answer a customer call.

I'd really like to see this implemented in the networks again as I would really like to have both a smart phone and feature phone active on the same number. Partly to preserve battery but also so I can easily switch between them to get some detox from the addictive nature of a smartphone without the need to swap SIM cards in and out each and every time.

I vaguely recall that function, VF-Spain implemented it. Each SIM had its own individual MSISDN, but they were mapped to a common number at the cost of mobile data not being available on any of the pooled SIMs.

If love to see this again too. I'd like a second phone in the car or
wherever I didn't need my much more expensive phone instead of having to
swap the SIM across.
All sorts of protection could be built in to help prevent fraud with the
second phone.

I don't see why this wouldn't be possible,  after all, EE already offer separate esims for watches and those share the number linked to your phone.

I wonder if you could link a watch esim to a phone instead, after all, it's just a normal esim.

@GruffRumble   It’s linked at account level so the watch gets the call/text or makes a call/text the watch and phone have their own numbers still.

It's a great shame UK networks don't support this. 

I am also an Etisalat customer in the UAE and they offer a multi sim subscription (up to 5 sims) which works really well. All phones operate on the same number but you set via SMS which phone you want to make/receive calls at any given time and they all share data. Works very well.
