The first thing you can do is to read the user's manual of your pocket wifi.
To use your pocket wifi, you need a Globe Tattoo sim (LTE or 4G sim)
your password for the wifi is either written in your manual or it is placed under the body or back cover of your pocket wifi.
To configure your wifi, You need to access your wifi's dashboard.
For huawei wifi, you need to install this app (Huawei HiLink) from Google Play.
For ZTE wifi, you need to install ZTE Wi-fi Monitor 2.0 from Google Play
default username/password is admin/admin
Hope this helps.
