Xperia SP C5303 Unable to connect to LTE/4G with freemobile (FR)

[ludo33700fr]

XPERIA SP C5303 is LTE compatible

My Xperia SP has sofware 12.1.A.1.205 installed with PC Companion in French (because i leave and speak french)

This is the last version Sony sends for this model. It install Android 4.3

I own a 4G/LTE line with freemobile (french)
4G has been activated on my mobile : Parameters/Networks/Network mode : 4G (prefered)/3G/2G

4G is activated

Howevec i am unable to connect to 4G network where some of lmy friends can with same provider and different mobiles.

Loking for this topic on internet, i found that freemobile expects 12.0.A.2.245 or 12.0.A.2.254 firmware.

Unless i missunderstand these expected versions are less recent ones, probably Android 4.2 o Android 4.1.2

Sony does not provide any topic to install theses firmware versions... and to come back whenever it fails working

For now, as i undestand, this 12.1.A.1.205 contains a major regression disabling 4G/LTE to properly work on my country.

Any idea ?

Should it really resolve to come back to 12.0.A.2.245 or 12.0.A.2.254 firmware ? How to ?

What to doc whenever it fails

Is your phone compatible with your carrier's LTE bands?

LTE band 1(2100), 3(1800), 5(850), 7(2600), 8(900), 20(800) - C5303

[ludo33700fr]

As far s i kwnow, C5303 is a model for Europe and supports 4G/LTE

c5303 has this bands available

2G: GSM 850 / 900 / 1800 / 1900

3G: HSDPA 850 / 900 / 2100

4G: LTE 800 / 850 / 900 / 1800 / 2100 / 2600

My provider freemobile (france) uses the 2600 MHz LTE/4G band

Check with your carrier if they have any LTE network coverage, also ask them if they have accidentally disabled LTE on your account, also it wouldn't hurt to get a brand new SIM card.

The good answer was there was NO coverage in the place i use to test.

Other providers cover this place but not free mobile

free mobile althougth provides a coverage map to answer this kind of question. Should have seen it before

In a place that is 4G covered, the C3503 had 27 Mbps download and 14 Mbps upload. Not perfect but it works

Thank you for the answers you gave.
