Apple Watch Impossible to Pair with Three

[Nadeem1]

For the past 2 days I've been bounced around Three's Support Network with no solution to a somewhat simple issue. It seems like the "Technical Support" team and even the "Senior Technical Support" team have no clue as to how to fix an Apple Watch Network Pairing issue. Instead of helping with getting the watch's cellular working they started reading me Settings to change on my iPhone which are completely unrelated to my watch. I have had to unpair/factory reset my watch about 5 times as apparently that will fix the issue. Now to the issue at question:

When activating the cellular service on my Apple Watch, I cannot get past the login page as I keep getting "There's a problem, At least one of the fields is wrong" even though all the fields are filled and correct. I have been stuck at this for ages and for sometimes I get through to the "Our Plan" page which says that "You've already purchased this plan" and asks me to "Activate Now". After clicking this button, it sends me to another error "There's a problem, System Error." 

Now it's a shame that there is no support the "Technical Support" team can give to a growing group of users who use smart watches and want to connect to Three. If a company is charging £7 to pair cellular service to a smart watch then it should work seamlessly and have a support sector who can help if needed. I think the infrastructure should be built out, tested on and validated before it is allowed to be used by consumers. If a service can't handle a watch unpairing because the IMEI's are the same (as I have read in other forum posts) then that service isn't ready to be released, let alone ask users to pay for it.

If someone can help me get this sorted, please can you reach out as I am considering changing providers.

I just had the same experience with the three agent in the chat..... holy s*** talking to chatgpt is 10x easier than this. 
I always start these conversation explaining in detail all of the things I have already tried, but still 30 minutes into the conversion he still shares a copy/paste of the basic SET UP GUIDE for pairing the watch.... it is bizzare. 
It then took me a long time to convince them to cancel the plan and credit me the £7 it cost. He kept only offering £5 'goodwill' and I had to explain in multiple ways how that doesnt cover the full cost.
Anyway, I now have an expensive watch I wanted to use without my phone, and I cannot do that. 
I am stuck in a contract for 13 more months, but I think it's time to move on finally.

Hi there. 

That's disappointing to hear. At which part are you getting stuck? What error are you seeing?
Can you also confirm which model of phone and watch you are using? 

Pete.

Hi, 

Its the same as the many people in here, the status just says 'no connection' no mater what I tried. 
I have tried all of the things people mentioned in here and what I've seen elsewhere, none of it worked. 

I would like to get it to work, but with how awful it was trying to get help and then trying to cancel the plan and get my money back, I have little faith in that ever happening.

I'm having trouble understanding at which stage of the pairing process this is at. The No connection error you've mentioned, is that happening during pairing? Is it on the phone or watch? What devices are you using? 

Pete.

I'm writing this in 2025, I've just bought an apple watch cellular and have come across the same issue that you were  experiencing in 2023. Seems like Three aren't bothered enough to ever fix the issue. So I'm returning the watch, especially when it cost £100 extra just to have the functionality.

I struggled with this. Spent hours + support didnt manage either. I changed my Three password to only letters &  dropped all numbers so letters only and signed out.
I then Power cycled my I-phone then back into the Watch App and it looks to have worked ok

IM having the same issue as you all -  Im extremly annoyed as i describe my issue then i have four or five diffrent calls with diffrent teams and then i get a call back set up from a tech team.

Then that tech team call me back and ghost me on the phone.

I have the recordings of this!

They do not solve my issue and then close the ticket to try and avoid the issue !

I have spoken with a lawyer and he is advising to take legal action to void the contract and move supplies.

My issue: When i try to set up mobile data on my apple watch ultra it connects to a three screen and then displays the following. "There is a problem. Please note that you cant progress to a new subscriton as you already have an existing one which is still in progress" now as i mentioned i have been through this before.

So things i have checked:

My iphone and watch are up to date

i have rest the watch muitle times i have rest the watch mobile data multipe times.

i do not have any other add ons that i can see on my end

I have rest my passwords and they done have any upper case or special characters

I have waited more than one billing cycle

i have paried an unpared i have cleared web browser settings

so what else can i try

Same here spent hours on pointless live chat following instruction that only made the matter worse. Reset repaired and now no network connection at all. I demanded a call with technical which was just as pointless. Wasted over two hours to be told go and visit a three store. Which I’m unable to do for a week. The systems on this network reflect the cheap prices I suppose. Time to move the EE!
