4G lost

Hello
I installed ROM Evolution4.7, then 5.3, a 5.4 and now 5.5
In 4.7, I had some problems with 4G,
when I close Wifi, I couldn't use 4G for WEB, only telephony (GSM) and no messaging or sms.
Perhaps wrong network Type (Bouygues Telecom) ? LTE/TDSCDMA/GSM/WCDMA
Many options for 4G but with LTE, no effect

Anyone have an idea to reactivate 4G
Thank you
