Can I order additional sims/activate samsung galaxy watch 4 on O2 Sim Only Unlimited Tariff?

[spamalam]

Are O2 still not able to share a plan between multiple sims?  Movistar / O2 in Spain has no issues (its called multisim) and I understand its the same company so not sure why this is the case.

I have a smart watch (Samsung Galaxy Watch 4 Classic LTE) and a phone and would like to share my plan/number so I don't have to carry my watch everywhere.  When I try to enable data it talks about getting a QR code to scan from your provider.

Thanks in advance.

Same parent, but Telefonica bought o2, and they dont offer the same technologies, in fact i would say Movistar struggle with Mobile Services a lot of the time...

You need to sign up to a data plan for the watch at £5 per month, and get an esim,...either sales can help with this or call into an o2 shop to get it setup. 

You contact them them on Social Media if that works best for you -on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG), Or you can call them on 0800 081 0255

I understand I won't be able to receive phone call those on the same number if its a separate sim?  That doesn't really work.  The problem is i can't use the o2es multisim since i'd be in roaming for too long.  I guess I need to go to another provider like EE?

Seems there's an option with an 'eSim', but it sounds like it requires your phone to be connected to the internet.

That is the way o2 have set it up.... 

You receive calls on the watch number due to how Samsung have set it up, so the phone needs to be connected to the internet and its a remote calling IP session to the watch for calls and texts...

EE do it a different way, but still not true Multisim, as no UK offers them anymore

No the way it is set up is that it's the same phone number on the watch, you just have to get it set up correctly and the call will come through to it @spamalam.

The eSim part means it is an electronic sim and not a physical chip that gets put in the phone.

Samsung watch setup.
1. Contact O2 and get them to set up Data and WIFI calling on your Samsung mobile, it's free but needs to be set up to use the watch. You can then turn the switch on in setting under connections.
2. If you need an esim the only place to get it now is at an O2 store, it's free at the store.
3. If you already have an esim you won't be able to set up your watch just by going through the process on the Gear app, it'll set up the plan in principle on the phone and watch, but it won't connect to the network so don't waste your time. Delete the plan and go to an O2 store.
4. The only way you'll get the watch connected is by going to the O2 store, sitting with the sales person and have them set up the esim and the plan, it's £5 per month for 1gb which is more than enough data.
5. Most store sales people haven't a clue about setting up the Samsung watch 4g, so have them give you the esim, scan the QR code let your phone set up the plan and then have them go into their system as if your purchasing the watch directly from O2, at the bottom of their screen (this is at an O2 store) there is a box that says set up watch plan, when they press that, it'll allow them to set up a watch data plan, as if you've purchased the watch from O2.
6. At that point and after the salesperson puts in all the info from the esim they gave you into their system, it'll take about 10 min for the watch to connect, you'll then need to go into the connection settings on your watch, turn on auto for data, turn on data roaming and then go to the network search setting on the watch and let it the watch search for the network, it'll then register it and you're almost there.
7. Next go to your mobile and in settings, advanced, turn on the switch to use your mobile data on other devices, make sure when you turn it on, it shows your Samsung watch at the bottom, tap and another screen comes up showing the watch is connected to your phone.
8. Then reboot your watch and your mobile and you're done. Test it by leaving your phone in your home and take a walk, the watch should connect and show the 4g symbol and the mobile calling bars, if you try and make a call and it doesn't work or says connect to Bluetooth, go back to step 7, and reboot the phone to make sure it's found the device, i.e. your watch. It will also say at the bottom of the watch, standalone, means your using the watch on it's own.
9. You're done. Just remember you can only get your Samsung Watch 4g connected by getting it done in the O2 store.

Good lord, that sounds excruciating. 

Thank you for the advice.

The problem is that very few O2 staff seem to have been properly trained on watch activation, so take the instructions with you and hold their hand through it.
