O2 smartphone used as "mobile hotspot"

24vtingle — Sat, 10 May 2025 15:14:31 GMT

Hi,
I have a Samsung SM-J330FN smartphone and its on a O2 PAYG thing.
The phone was bought in 2018.
Every now and then I am on the road and need to do a 1 hour Teams video call on my laptop.
So I wish to set the smartphone up as a "mobile hotspot" and do the teams video
call on my laptop like that.
(The smartphone doesnt run Teams)

Do you think the smartphone battery will last long enough for being used as a "mobile hotspot" for 1 hour?

We cannot possibly speculate on that @24vtingle as it depends n the battery's condition.

Why don't you test it yourself ?

Keep phone connected to power ...

@24vtingle

Another question to ask how much data do you have and is it an Audio only teams call or a Video Teams call, as Teams is very awkward about bandwidth... and Microsoft recommends a minimum of 1.5 Mbps download and upload speed for one-on-one calls and 4 Mbps for group video calls.

So I would suggest finding somewhere with Wifi rather than relying on Mobile Data

It might be worth updating the phone as its over 8 years old (they came out in 2017)

Thanks, I have 10GB of data, sounds enough?

(i bought a £10 data SIM and it gives you 10GB)
The alternative is to buy a 24V 5Ah battery and a 24 to 12Vdc 2A power
supply and just use my mobile router when out on the road.

It sounds like no smartphone would be able to do a 1hr Teams call anyway?
(battery would run out or not good enough upload/download speed?)

@24vtingle

Depends on how long your call is as your 10GB could disappear quick as per the below:

Audio-only: 40 MB per hour
SD Video: 500 MB per hour
HD Video: 1 GB per hour
Full HD (1080p): Up to 1.3 GB per hour

Mobile can do it, but better as Voice Only,

All my meetings are over Teams these days and it's used multiple times a day in the car.

I have no need to keep connected to power and don't even use 5gb a month on mobile data in total.

Your 10gb will be fine for many hours of audio Teams calls @24vtingle
