About this app

MASTER 5G lets you lock the bands of your Huawei 4G and 5G router and improve its signal right from your phone over your local Wi-Fi, without digging through the router's web settings.

Main features:

• Band Lock: lock 4G LTE and 5G NR bands, pick carrier aggregation (CA) and the primary band, and verify that the router really applied the lock.

• Cell Lock / PCI Lock: pin the connection to a specific tower by PCI and EARFCN so the router stops hopping to busy or weak cells.

• Live signal monitor: RSRP, SINR, RSRQ and RSSI for 4G and 5G with clear levels (excellent, good, fair, poor) to help you aim the router or an external antenna.

• Connected and neighbor cells: see active and nearby cells exactly as the router reports them, sorted from strongest, and lock any cell with one tap.

• Smart optimizer: suggests the best band combination for your location based on the real signal.

• Statistics: live download and upload speed, data usage per session, day and month, and a live signal log.

• Signal guide, Arabic interface, light and dark themes.

Supported devices:
Tested on Huawei 5G CPE 5 (H155-381) and works with most Huawei HiLink routers such as 5G CPE Pro, B535, B818 and B628. Some features depend on the model and firmware version.

Security and privacy:
• The app talks to your router directly over your local network and never sends router data or passwords anywhere.
• Login details are stored encrypted on your device only.
• The app shows ads through Google AdMob; see the privacy policy for details.

Notes:
– Requires a Wi-Fi connection to the router and its admin username and password.
– This is an independent app, not affiliated with Huawei; the name is used only to describe compatibility.
