I’m on o2 and have an iPhone which is probably around 4 years old if that’s relevant, but so much of the time I can’t get any mobile internet. Like it always shows as having bars/ and either 4G or 5G but it just won’t connect. Sometimes I think it’s because I’m someone too busy (a traffic jam or town centre) and sometimes somewhere too quiet or remote but it feels like it’s just really unreliable and causes problems for using google maps when driving, paying for parking with apps.
Is o2 particularly bad? Is having an older phone the problem?
