Using EE SIM on DrayTek Vigor2862Lac LTE Router

[smithdj5]

Hi,
I've recently bought an unlimited EE SIM at £33/month because EE has faster speeds where I live compared to Three who I've been using for the last 2 yrs. I have no fibre at my remote rural address and standard wired internet is useless (less than 1 Mbps download). Luckily, mobile signal is fairly good.

Therefore I'm using a Draytek LTE router into which I just insert a SIM. It works great with Three but I swapped to EE hoping for better speeds. I received my SIM 2 days ago, it works fine in an iPhone and an old Samsung phone but I can't get it to work in my Draytek router. As below pic, the Three SIM connects no problem but with EE I get "registration denied".
In other parts of this forum, I've found the APN settings but they don't work for me !
Does anyone else on this forum use a Draytek router and what APN settings do you have. 
I've been on a Draytek group on FaceBook. One guy says he has an EE SIM in his router but he leaves the APN entry blank whereas the info on here says APN entry should be everywhere ?
Any help please ?
Three connects - EE denied !

I already posted a screen shot of the complete APN page - see my reply 4/3/2023 at 09:36AM
The fields show settings for my Three SIM as obviously I'm having to still use my Three SIM because the EE SIM won't work !
However, I can confirm I have tried these settings for EE, which don't work.
For password I also tried "ee" instead of "secure" as someone on another forum made this suggestion.

I don't see it but NM thanks for putting out now.

That all looks right other than if there were an Authentication Type I'd make it PAP.

Thanks, I already tried that and makes no difference.
I have a call scheduled with the router manufacturer support on Friday morning. They are doing a remote desktop to look in depth at settings. Hopefully they will find something. 
I find it very frustrating with EE that -
1) I am paying for the top price unlimited data SIM and despite trying just about everything it won't connect to my router
2) The official EE so called "Technical Support" line told me they don't know the APN settings and in any case they are not allowed to give them out !!  Obviously they are available on things like this forum but it is pathetic that the official tech support will not state APN settings
3) In contrast my Three SIM connects no problem and the APN settings are easy to find on the Three web site
I appreciate your help but I am guessing you are not an EE employee so EE seem to rely on volunteers solving technical problems

I will post on Friday if the Draytek support guy finds the solution

[XRaySpeX]

Yes.

Hi - sorry for slow update. I finally got a solution thanks to direct help from Draytek support who remoted in to my system. Good news - my EE data SIM is now working in my Draytek 4G router and I'm getting a much better speed than Three 😁
The solution surprised the Draytek guy and I'm sure will surprise you !
He left everything blank - APN name, username, password.
All blank and it works great !
What a shame that the so called official EE technical support available after a long wait on the phone could not have given me this information. I assume someone with a technical brain at EE would actually know this information. If EE wasn't faster than Three I would have cancelled but as they are about 2X faster than Three they have me !

Well, I'm blowed! I would never expect that & so would not expect EE CS to have guessed it.

Must be some quirk of the Draytek. After setting it blank did it somehow populate the APN with the correct values? 

[smithdj5]

I don't think it self populated because -

1. if I look at the settings now they are still blank
2. there is a check box "do not auto populate" which the guy wanted checked

So my guess is that EE have changed something at their end so that their system simply knows if a SIM is entitled to a connection. After all, every SIM has a unique ID so when a SIM tries to connect to EE they must be able to cross reference their customer records to see if it's allowed ?
Because if the username / password were truly all that you needed then they are hardly secret so anyone could connect !   I think they've just decided to base authentication totally on the SIM itself.

You could be right! I just defaulted an almost blank Profile/APN in a mobile router & tested with EE-specific SMS OK. But it also does work with the accepted EE Profile/APN which yours doesn't.
