I have just purchased the Samsung Ultra and when trying to pair it with my phone I am getting the following error code message “E53306 Your airtime is not compatible with the Smartwatch Pairing service - Please call your contact centre”

Looking on the forum I can see these types of questions were asked over a year ago, have you guys still not moved with the times???

I can see other providers have this service and yes they charge a monthly fee so I’m very surprised if you haven’t, somewhat frustrating that I cannot use my watch as I wanted due to my provider not providing the service!

Only EE, O2, Vodafone and THREE offer watch plans. You will have to switch to one of those networks if you want a watch plan. Just bear in mind their phone plans are considerably higher than MVNO’s.

Hi @kimberleybreckons,

I completely understand why you’re frustrated, you’ve just invested in a Samsung Galaxy Watch Ultra, and instead of enjoying it straight away, you’re being stopped by an error that makes it feel like we’re behind the curve. I’m really sorry you’ve had this experience.

Samsung watches that support LTE/mobile data require eSIM smartwatch pairing. At the moment, iD Mobile does not support eSIM for wearable devices, only for phones. This means the watch can still be used fully via Bluetooth/Wi-Fi, but it cannot be set up with its own mobile data plan on our network.

You’ll still be able to use your watch for:

Notifications

Fitness tracking

Calls/texts when your phone is nearby and connected via Bluetooth

Samsung Wallet, apps, etc.

Thanks,

Luna

I don't know how much you need it, a few years ago I had it connected in THREE and I paid an additional £7 a month... after a few months I gave up because it didn't meet my expectations.

Hello. That error means your current plan does not support the Smartwatch Pairing service which allows your Samsung Ultra to use its own number connected to your phone plan. Your provider simply has not enabled this feature yet which is genuinely frustrating given how long others have offered it. Best option right now is to call your contact centre directly and ask if there is any timeline for rollout or whether upgrading your plan unlocks it. In the meantime your watch will still function normally for fitness tracking, notifications and all other features over WiFi and Bluetooth, just without the independent calling feature.
