Z2 don't getting H+/HSDPA

[meloferz]

Hi all... I bought my Z2 that was for UK market, and I'm using it in Paraguay with Vox carrier, they use 900 MHz for 3G as most part of Europe. But... I can't get H+ signal 😕
Flashed a GEL customized on my Z2, that my former Z1 Compact had, and with that phone had no problems using H+. Any suggestions to solve it? It's weird because with another carrier can use H+ signal that's works on 850 MHz

It won't work, it's a hardware not software limitation, you can flash other firmwares but it won't work.

My Z2 model is C6503, that is compatible with BC8/900 MHz, I got H/HSPA signal, but not H+/HSDPA. So... It's not a hardware limitation, like I said, it's weird because even with UK firmware (don't remember what customization was), I just got H/HSPA and not H+/HSDPA with my carrier

3G bands HSDPA 850 / 900 / 1700 / 1900 / 2100 - D6502, D6503, D6543

4G bands LTE bands

1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 13(700), 17(700), 20(800) - D6503

1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900) - D6543

It should work just fine, you might want to get a brand new NANO SIM Card and also, double check your carrier/network's 3G, H+ and LTE coverage.

Thanks anyway, I can deal with that... HSPA is not to slow, and I have LTE with my carrier...

Excellent

Got an answer from my carrier Vox (Paraguay)... They said that have problems with certain phones, and mines is in the list... I just can use H/HSPA and LTE for now.
