Sporadic as in, it sometimes works, and sometimes not.
Wifi is fine, but mobile data (4G/LTE) is not. With the same SIM card, mobile data (LTE) works fine on LG Optimus G.
In my case... my sim is 3G..but i've set in Mobile Network is "LTE/WCDMA/GSM (auto connect)" at first.. then i found out my data connection same with u.. sometimes on & off... telco company advise me change to "WCDMA/GSM (auto connect)". Since my operator line area still not available for LTE service. After i changed it.. then works fine.
U try to change first, then we'll see..is it ok or not.
Here in U.A.E i was facing the same issue as a work around i go to SETTING , MORE NETWORKS i then MOBILE NETWORKS and in NETWORK MODE manually select WCDMA/GSM as off course i wont able to get LTE but data speed is much better and no signal problem what so ever.
Is there a code from dialpad to get into backend settings? For instance, with my other phone (Galaxy Note 1), I can dial *#*#4636#*#* to get into phone settings for more options for network connection.
