Will the MX5 get 3G and 4G in Australia?

Will the MX5 get 3G and 4G in Australia?

I have MX5 model M575M. Flyme It gets GSM signal. I have been unable to receive 3G or 4G. I have tinkered with the settings for a few hours.

My signal provider is Optus. The Sim card is 4G capable and receives 3G in another phone.

On the box it says:
FDD LTE(1920-1980/1710-1785MHz)

The towers in my location are as follows. O means Optus, TO means Telstra and Optus.
O 5700008 0.94 km
2G 900MHz
3G 900MHz
3G 2100MHz
4G 700MHz
4G 2600MHz

TO 5700006 2.9 km
2G 900MHz
3G 850MHz
4G 1800MHz
3G 900MHz
3G 2100MHz
4G 700MHz
4G 2600MHz

TO 5700005 2.91 km
2G 900MHz
3G 850MHz
3G 900MHz

O 5600007 29.07 km
2G 900MHz
3G 900MHz
4G 700MHz

O 5433001 30.67 km
2G 900MHz
3G 900MHz
4G 700MHz
4G 2600MHz

O 5485003 35.88 km
3G 900MHz
4G 700MHz
4G 2600MHz

3G yes. Probably you will have to set your access point settings right. In settings Look for network and APN settings. Contact your provider for the right settings.

4G if you are lucky, All I know is that Australia uses FDD-LTE and the frequencies you posted do not match.
Edit: Only this one should work: TO 5700006 2.9 km 1800Mhz. The higher the frequency, the lower the range and permeability, so if you are inside your home, it could not get through.

I think you would get 4g in large open areas, like in your town square or something.
3g everywhere.

Hi, thanks for the replies.

Upon looking into it further and chatting with Optus technical support for about 2 hours, they had me observe the following information taken from: http://phonefullspecs.blogspot.com.au/2015/05/meizu-mx5-specs.html

Meizu MX5 Specs
2G bands GSM 850 / 900 / 1800 / 1900
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE band 1(2100), 3(1800), 7(2600)
Speed HSPA, LTE Cat4 150/50 Mbps

The tech had me reset the APNs, power cycle, cycle 3G First 4G First, I’ve cycled flight mode, changed sim slots, cycled mobile data switch, etc. Every time the phone does connect it connects to EDGE instead of 3G.

Last resort factory reset, same result.

Further information: I traveled to a regional area the other day where there is only 3G and no GSM/EDGE. I had no signal. (this is how I discovered this problem actually as I am required to travel around for work)

I am open to all suggestions. Perhaps entering the APN manually I might try, maybe something to do with the keyboard translation?

Will attempting to flash International firmware help at all? The tech said the firmware shouldn’t be the problem though.

Is there a way I can see what signals the antenna is receiving? Like an MMI code or something like that?

After further investigation, I am convinced that the ‘C’ type of Flyme firmware has blocked the required bands.

Info on different firmwares:

"AOKP Admin 2 months ago
Basically it is 1:1 the same chip. However the Flyme engineers were so nice to block some bands on some firmwares.
So yes, theoretically the bands are the same, however some bands are disabled on the chinese MX5."

Difference between A, C, U and I Firmwares
A = Generic Works on all devices. U = China Unicom Same like A, but with carrier specific apps Might have locked bands. C = China Mobile Same like U. I = International Only available for I devices, can be bypassed.

Some band info:
“the most widely spread networks in Australia, with 700MHz needing a band 28 compatible device, 850MHz on band 5, 1800Mhz using Band 3, 2100Mhz on Band 1, 2300Mhz on Band 40 and finally 2600MHz on band 7”

From this information I have the question:

  1. Does the ‘A’ firmware block the bands like ‘U’ and ‘C’?

And if not:

  1. To avoid the hassle and potential risk of flashing ‘I’ firmware over my current ‘C’ , can I download ‘A’ and perform a regular update, which will allow future OTA updates, and magically fix my problem?

@dazers Firmware “A” has all the bands, like the maximum you can get out of your phone, just like the Firmware “I” has.

If you know what you are doing, you can go to the Engineering-Mode, but don’t mess around in there, and have a look at the bands of your phone.

Don’t mess around in the engineering mode! You will get yourself into trouble!
Engineering mode: just add a * in the end.

and get’s you in here:

Awesome! Thank you very much for help, and everyone else on the forum. The update to A firmware now allows a strong LTE signal with Telstra and strong HSPA 14.4 Mbps signal with Optus.


Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
