Good to know its working. If the ZTE device came originally from the Three network then it is possible they may have had a special firmware that limits frequencies.

I had the same problem with my Huawai E5776 http://forums.thinkbroadband.com/mobilebroadband/f/4... even though their 4G mast is only a couple of hundred metres away.

I bought an O2 SIM and 4G works fine. Then, total madness, found out that although erected by Vodafone, this mast is shared by O2!

With the O2 SIM, all I did was insert it in to the E5776 and away it went on O2 4G

Cheers!

Not unusual for masts to be shared by operators, there are masts with Voda + EE(orange) and masts with O2 & Three, and masts with all four operators.

There are also two infrastructure sharing organisations, CTIL (www.ctil.co.uk) (Cornerstone Telecommunications Infrastructure Limited) and MBNL (www.mbnl.co.uk) (Mobile Broadband Network Limited).

CTIL is an infrastructure sharing company half owned by Telefonica (O2) and Vodafone.
MBNL is an infrastructure sharing company half owned by EE and Three (for 3G services MBNL does more).

These agreements have come about due to the costs of sites and the need to expand coverage to meet the agreements made with the government (some may remember when Cameron couldn't receive a call in Devon - he was obviously on the wrong network!).

or he was on 4g

all sorts of issues with calls on phones that have 4g enabled as sometimes it fails to correctly drop to 3G and [censored] up the connection and hangs up after 2-3 seconds or network gives up trying to connect to to phone after 5-7 seconds and you get voicemail (works fine if the call drops to 2G from 4G witch my windows phone does/did quite often, until i just set highest speed as 3g so rarely drops to 2g now)

had one company that was going to move all there phones over to another network because voice calls was been very problematic (ee 4G) just told them to set all the phones to 2g/3g auto, a week later when i come back mostly no problems at all (odd locations where signal was acutely the problem)
they was on an old orange or t-mobile business group plan before and as they dont allow 4g on them contracts they never had problems before until they change the plan which had 4g and was running into problems where calls would not connect if the other person was on 4g network as they was failing to step down to allow voice call

EE and 3 both allow calls over 4G.

No need to step down your handset just needs to have the option enabled to take calls over 4G.

Certainly my iPhone makes virtually all its calls on 4G.

Android/windows phone need EE branded firmware or a iphone (most people have cheap android phones not iphone)

the problem here is step down to 3G does not always work on inbound calls (3G it self is not 100% reliable and been able to connect the call inbound)

Have you observed these issues with EE 3G handover recently?

I only turned on VOLTE around 3 weeks ago when I got a new phone, prior I have had fallback to 3G for around 2 years with only a couple of calls not coming through. In 2012 when EE just started 4G virtually every phone call in heavily populated areas (oxford street london etc) went to voicemail but that seems to be entirely resolved for me.

I did experience it at a music festival over the summer but I got an SMS telling me they had called and was able to dial back.

i still get the odd call thats broken (more so cracking audio now, i turned off 4g set 3g as highest speed as i use all my data on my 3 sim) for business use i would not recommend 4g been enabled on the phone unless it has 4g calling support (witch is likely fine as runs over the data itself, even very low 4g signal seems to work very well on data side)

ee/orange/t-mobile is one of the number of networks that have it as standard for Very long time (missed call text) O2 and vodafone only in last 5 years i beave

3 still lacks missed call notification text and they need it more than any other network, good thing is they don't block call forwarding so i use Hullomail (not sure why they don't enable it on there voicemail as it supports it i guess they don't want to expose how many calls fail to connect)

Virgin mobile i think has just added missed call notification text (need to test it) i would of been with Virgin mobile probblery years ago if they allowed call forwarding or had missed call notification text

you cant rely on people leaving a voicemail message (i know you get people saying call must of not been important if they did not leave voice mail but for work related a missed call is lost money) missed call notification text should be standard on all networks (you have to assume it does not ifs its a virtual provider) the networks that do support it have the option to disable it if for some reason they dont want it
