Dreaded E53305 error

Matt_UK — Thu, 09 Oct 2025 06:13:07 GMT

I upgraded my Samsung watch 6 classic that was on a pay monthly plan to a new Samsung Ultra with watch on a 2 year plan. I removed the mobile plan from the watch 6 and reset it. Added the new watch and when I went to add a mobile plan I got the E53305 error.

An hour on the phone and 3 hours online chat with support has got me nowhere. I was told to wait 24 hours, reset the new watch(!) and then told to wait for my billing cycle, which was yesterday. I did tell them the solution elsewhere had been to remove the plan and then add it again at the billing cycle but they didn't listen.

Can anyone help please?

Hello there.

You mentioned the team told you to wait for the billing cycle, it sounds like this is the process you are referring to seeing online. If you don't think it was done properly, it might be worth contacting the team to ensure the addon is removed so that you can wait for the billing cycle and then re-add it.

Pete.

Still no joy after another hour. Told the 'technical supoort' what was required and instead they are running a deep dive on my account to see whats wrong and will report back in 7 days. Seems like a good way of doing nothing and hoping it starts working all by itself.

Hi @Matt_UK,

Did the team manage to get this sorted out for you the following week as mentioned, or what happened next? Please let me know if you still need any help with getting your smartwatch pairing service sorted out.

Thanks,
Jonathan

Hi, they have got back to me, several times, but it's the same every time. Watch is still failing to pair. Any help would be great.

Still the same, despite multiple calls telling me it's been resolved.
