Even after the latest update today, I'm still having the same problems. 4G isn't possible at all, 3G goes off and on within seconds. But the biggest bug is, that once I turn off data connection, I can't turn it back on without restart the phone.
Since these issues don't occur only to me and not only in one particular country (it happens in France, Israel) and Germany where I'm from, it's a problem of UMI Z. Hopefully a softwareproblem that can be solved with the next update !!!!
I don't have these problems with my old ZOPO with same SIM at same place.

Same ..... In Ireland , using Three Ireland....... Line keep on 3G and Roaming ......... Maybe is cheap Helio processor problems........ I always prefer snapdragon to be honest, 4G much much stable and strong !!!

"Is UMi Z 4G LTE capable?

Yes, UMi Z is 4G LTE capable

These are the 4G LTE bands that supports the UMi Z :
1800

Those are all the 4G bands in operation in Denmark, but 800 MHZ is just for TDC or companies that have roaming deals with them.

So no 800 MHZ for me, and thats alright by me as TDC is pure evil and can not die fast enough.

Since the first update (the last one was the third) i don't have any issue with 3g in rural areas or 4g when in some citys. Im from Portugal BTW. Also, I can turn on and off the data connection just fine.
