Can someone at giffgaff (wont hold my breath for that one lol) explain to me whereas I now get no signal at all using my giffgaff SIM because the "local" mast is obviously down again, but using my new Lycamobile SIM (also runs on O2) I get one or two bars. This is from standing outside, I get no signal indoors. So not only do you have lower priority on the network compared to O2 on giffgaff, you also have a lesser signal strength, that makes no sense to me.

If there are other masts in your area, a phone will try to connect to any mast it can reach but those masts will have extra loading because of the mast that is down.


In overload conditions, it's not possible to predict which (if any) mast you connect to because the loading on masts will vary continuously as other users connect or disconnect.


So, you might get stronger or weaker signals, or no connection at all -- you would have to perform a suffiiciently large number of disconnections and reconnections with both sims to get any meaningful conclusion whether you were just lucky in connecting at precisely the right time or whether there is genuinely any priority allocation.

Thanks @harrrrrry. Bear in mind though I'm on a little island out in the sticks - there are very few phone masts here at all! The "local" one which is down I refer to is about 13 miles away, and that is also behind a hill. So now the weak signal I'm getting is now from even farther away. Three is still working as normal I'm using it now - mobile broadband (outside antenna), and the Three SIM in my phone is working too (outside).

A lot of it just depends on luck of the draw some areas it is much better than others with certain networks all depends on the masts and where are located compare to where you are using your device

I would try swapping the phones and using the same phone, and not using a case. Also the way you hold a phone can adjust the signal. Many different things can effect a phone and its bars

@masterluke does it do the same thing in a different handset? If so then the likely culprit (as you suspect) is prioritisation.

The O2 network has 3 priority levels - putting it horribly simply this means; in an area of strong O2 coverage there shouldn't be any obvious difference in signal performance between priorities, whereas in an area of weak O2 coverage signal will be up and down (if not off completely) as "lower priority" connections get kicked off overloaded masts first (or 'downgraded' from 4G to 3G, 3G to 2G, or 4G to 2G signal as available).

telifonica who own O2 and giffgaff put giffgaff at the bottom of the pile

It may be the mobile phone difference. I've got a backup giffgaff SIM (used to be in my tablet), which is in a basic phone (not a smartphone) and I get better signal (bars) in that then I do my main giffgaff phone (Samsung Galaxy S8). Can be quite frustrating actually.. But I have the luxury of having WiFi here. It can get very annoying when I'm out and about though without WiFi!
