3G, E or GPRS question - what is the difference?

[Anonymous]

Hi,

I've had a Iphone 5c since launch day and I was really impressed with it, particularly it's signal strength and internet speed on 3G.  Since the IOS 7.0.3 update, I can't keep 3G, and drop to E or even GPRS.  I can't recall ever seeing this before the update or on my Iphone 4.  Have they split 3G into 3 groups of strength and that's why I'm seeing E or GPRS?  I'm also disappointed that I have a 4G ready phone, 4G ready sim card, but I couldn't get better than GPRS in Sheffield city centre!  I've read a few threads on here about data connection on the newer models, and just wondered if the introduction of seeing E, GPRS or 3G is just that, a new display thing?

It should be
It may take a few weeks though.... I'm in Cov and we had an intermittent signal for about 4 weeks whilst the 4G upgrades were being done 😞

It is worth it I personally find o2 4g very good where I have tried it
