Hi guys .....I have ATT I337 using deadly venom 4.3 jelly bean and recently my network acting up under settings> more network>mobile network ....normally auto connect on LTE/WCDMA/GSM but recently keep changing to WCDMA/GSM only and keep saying ATT network not register......or mobile network not available when I try to make or receive call..... I Called ATT and got new Sim card and tested it out with other phone ....Sim card work just fine......and tried different baseband/modem is still acting up or keep changing to WCDMA/GSM only auto connect mode.....any idea how to fix this? Seem to me like signal keep dropping off and when there is no LTE signal. ....it auto pickup WCDMA/GSM only so when I tried to make or receive call keep saying that error......
