Can i use my Samsung Smartphone with my EE account?

[treez]

Hi,

I have an EE monthly account which pays for my useage of my dumphone, and for my mobile router.

Obviously i use the mobile router with my laptop. I never use the mobile router SIM card for phone calls ( i dont even know if i can). The mobile router has a 12V 2A socket which is powered from the mains via the mains power supply.

I also have a Samsung SM-J330FN Smartphone which i (possibly unwisely) bought with a 6 month pay-as-you-go in 2018. It was on pay as you go with O2. I have barely ever used  the smartphone.

I  barely ever used the smartphone as i always have my laptop with me. (i am just charging the smartphone  up now and hope the batteries arent dead). However, i sometimes need to do Teams job interviews (with camera ON) when i'm on the road, so the smartphone would  be good for that. (only say a few times a year for these interviews, but it would still be very handy for those few occasions). Incidentally i also have an Amazon Fire, which i never really use....but i sometimes use it with the mobile router though...i wonder if i could use that with my mobile router's SIM card for Teams Interviews when i am on the road?

I believe its not on a network now (?) and may not  still be the same phone number i bought it with(?) The IMEI number is written on the back of the phone though.

Can i simply put my SIM card from my dumbphone into this Smartphone and use it?

@treez : I'm not clear whether you want to use the SIM from the dumbphone or the SIM from the mobile router in the Samsung Smartphone. In principle you should be able to use either in it for data, which is what Teams would use. If the SIM in the mobile router is on a normal contract you would even be able to make calls & texts from it w/out any extra charge.

1 thing to be aware of is the Samsung is so old that it might be locked to O2 & would need to be unlocked by O2 before an EE SIM can be used in it..

Thanks, may i ask what you mean by a "normal" contract?

The router is called a " data SIM" contract, and the dumbphone is on a "Mobile SIM" contract.

I am worried because i have had bad experiences trying to get phones unlocked by o2 in the past......they tell you they will unlock it in 24 hrs...but just fail to do so....and keep failing to do so every time you ask them.

Is there a definitive way to unlock from o2?. For my dumbphone i literally had to buy a new dumbphone.

If you put a data SIM in a phone you'll have to pay for any calls and texts you make from it. 

Only O2 can unlock an O2-locked device.
