❓ Help Huawei b315s 936 lagi nag red 20-30 mins interval

[danixmarie]

Huawei B315s 936 lagi nag red 20-30 mins interval. If nag re-red sya, i change it nalang sa network from 4g pag nag red e set ko nlng sya to 3g. Super hassle po sya as in. Smartbro po gamit ko na sim. Sino po may alam on how to fix this.

Ilagay mo na lng sa auto. Para kusa na sya maghanap kung 4g or 3g ba
