SIM Card troubles in Router

[Mlawrence]

I have been having teh same issue over the last couple of weeks, 

I have a normal SIM with unlimited data/call/texts and it been working fine for teh last year,

I use the SIM within a TP-link AC1200 Archer MR600 and is used for DATA only, as I say been working fine for approximately 1 year, it’s now stopped working so far, I have tried the below; 

• Call O2 they carried out some re configurations on the back-ground data,
• O2 issued new SIM
• O2 had to set up new SIM as it is in a Router.
• Spend a couple of hours with TP Link checking the Router, did a update, checked setting – All OK
• Placed the new SIM in another device to check setting – SIM not picking up any internet,
• Called O2 to run through again, now waiting again for a call back from O2 specialist to no doubt do the above again,

So for 5 days in and no further along,

The first tech guy in call centre said I need a fragmented SIM none of the others seemed to know what this is and said a normal SIM should work fine, I don’t want to go to a DATA only as O2 don’t offer unlimited DATA only SIMs, I currently use more than the 150mbps downloads as I am trying to work from home along with my wife (also working from home) and 3 kids also doing schoolwork.

Every time you call it’s a different person and you have to start from the beginning and explain again, hours of time not working.

Anybody now what the problem is or has any further guidance that I can then pass on to the O2 guys.

@Mlawrence 

The system has blocked you for using unlimited data phone sim in a router which is not allowed in the T&C's.

You have to use a data only sim in a powered router.

[Mlawrence]

why has it been working fine for a year and nobody in the call centre has said anything, i have even stated what you have posted before to them and they said its not a problem.

@Mlawrence 

I can only guess the system has only just noticed.

I can't answer for O2 unfortunately, but I'll try and find the relevant T&C's for you.

Edit to add:

 3.3 Unlimited UK Data sold on handset or SIMO contracts must only be used in mobile devices that do not require to be plugged in order to work. Any O2 mobile broadband Unlimited UK Data tariffs must only be used with the devices that they are sold with. Where other devices are used that do not comply with these terms, we reserve the right to transfer you to a more suitable plan.

Your point on the TCs is noted and this will be highlighted again when I speak with O2, but I would add the below further information in regards to the sim DATA download speed, 

• when working fluctuates between 25 to 30mbps, good for working
• now and the reason for me raising the questions is that it is now operating at 0.5mbps, can just about carry out a VC.

 so it is working just a speeds that are unusable, if its was a TCs problem there would be nothing, surely.

Also strange how they have only just noticed as it the contract is coming up to a year and needs renewing

@Mlawrence 

Let us know what O2 says when you speak to them please.

[Mlawrence]

Not a problem, will do,
Just very confused as the moment and it is taking so long to get resolved,
Question, can a O2 SIM card be changed remotely eg can my SIM be changed to a DATA only contract only or do they need to send a new SIM and reset it up again.
PS thanks for your help

@Mlawrence 

No new sim required as the tariff is updated on the system so your current sim would be updated automatically.

O2 really letting me down, still cant confirm what the problem is and have now said i have to wait until the 16th, more time not being able to work. 

no communication i have calling them to get updates,
