Connectivity and compatibility16

Mobile network — what it means The generation of the cellular network the router uses to get internet from the SIM card. 4G+ (LTE Advanced) combines several operator frequencies for more speed where the operator supports it; 5G needs 5G coverage and a suitable plan. With weak coverage the router falls back to 3G if it supports it.	4G LTEThe maker states the network as "4G/3G" with up to 300 Mbps; the 4G+ / LTE Advanced designation and modem category are not given on the official page. Falls back to 3G where 4G is unavailable [1]
Mobile download rate (max) — what it means The theoretical maximum for receiving data from the operator's network, set by the LTE modem category (e.g. Cat 4 — 150 Mbps, Cat 6 and Cat 7 — 300 Mbps). Real speed depends on the operator, plan, network load and signal level and is usually noticeably lower.	300 Mbpstheoretical value; actual rate depends on operator, network conditions and distance [1]
Mobile upload rate (max) — what it means The theoretical maximum for sending data to the operator's network. It matters for video calls, uploading files and security cameras streaming video through this router; real speed is lower and depends on the signal.	100 Mbpstheoretical value [1]
LTE frequency bands — what it means The band numbers the modem works in, e.g. B3, B7, B20. The router gets 4G only on the bands your operator uses, which the operator can confirm; in Europe 4G most often runs on B3 (1800 MHz), B7 (2600 MHz) and B20 (800 MHz). Regional versions of one model can differ in their band set.	Not stated by the manufacturer
SIM card format — what it means The SIM card size the slot takes. If the format differs, the operator can replace the card or an adapter can be used; eSIM is a built-in card activated with the operator's QR code.	Micro-SIM (3FF)1 × Micro-SIM (3FF) slot [1]
Max. connected devices — what it means How many devices can join the router's Wi-Fi at once, per the maker; any beyond that number will not connect.	32 [2]
Wi-Fi generation — what it means The Wi-Fi standard version: Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac), Wi-Fi 6 (802.11ax), Wi-Fi 7 (802.11be). A newer generation brings gains in speed and with many devices only when phones and laptops support it too; older devices still connect but use their own standard.	Wi-Fi 5 (802.11ac)compatible with Wi-Fi 4 (802.11n) [1]
Wi-Fi bands — what it means The bands the device broadcasts on. 2.4 GHz reaches further through walls and is needed by many smart devices that work only on it; 5 GHz is faster but fades more behind walls; 6 GHz has the least interference and only newer phones and laptops support it.	2.4 GHz, 5 GHz [1]
Combined Wi-Fi rate (class) — what it means The sum of the maximum Wi-Fi link rates of all bands between the router and your devices, per the maker. On a mobile router internet speed is usually limited by the mobile network rather than Wi-Fi.	1167 Mbpssum of 2.4 GHz 300 Mbps + 5 GHz 867 Mbps (theoretical values) [1]
Ethernet port count — what it means How many RJ45 sockets the router has. Pocket models usually have none; on desktop ones a computer, TV or another router plugs into the port.	0the spec sheet lists only a Micro-SIM slot and a Micro-USB port as interfaces [1]
External antenna connector — what it means Whether there are connectors (e.g. TS-9 or SMA) for an external 4G antenna. At a country house or in a village with weak signal, an outdoor antenna aimed at the operator's tower noticeably improves reception.	Nobuilt-in 4G/3G main and diversity antennas; no external antenna connector listed [1]
WPA3 encryption — what it means WPA3 is the current Wi-Fi security standard and better protects the network password against guessing. Without it the device uses WPA2; some older smart devices connect only to WPA2, so a mixed WPA2/WPA3 mode is usually available.	Nosecurity modes: open, WPA2-PSK, WPA/WPA2-PSK [1]
App — what it means The maker’s app used to set up and control the device.	HUAWEI AI Life [1]
Fallback network	3G [1]
Wi-Fi rate per band	2.4 GHz: 300 Mbps; 5 GHz: 867 Mbps (theoretical) [1]
Wi-Fi security	open, WPA2-PSK, WPA/WPA2-PSK [1]

Model and version3

Device type — what it means A pocket router runs on a battery and fits in a pocket — for trips, the car and a country house. A desktop one runs on mains and stays at home, often with LAN ports and external-antenna connectors. A USB modem with Wi-Fi is powered from the USB port of a laptop, car or charger; an outdoor unit goes on a facade or mast, closer to the operator's tower.	Pocket, battery-powered [2]
Colour — what it means The housing colour of this model. Other colours in the same series are separate products.	Black [1]
Memory	RAM 256 MB DDR, ROM 256 MB NAND [1]

Power7

Battery capacity — what it means The built-in battery’s rated capacity. Run time also depends on how the device is used.	1500 mAh3.8 V, typical value [1]
Battery runtime — what it means How many hours the router shares internet without recharging, per the maker; the test condition (typical use, number of devices) is in the note.	6 hup to 6 h of continuous use, Huawei lab data; varies with network and usage [2]
Removable battery — what it means A removable battery can be swapped for a new one when it wears out, or you can carry a spare. A non-removable one is replaced only at a service centre.	Yespacking list: "Rechargeable battery (removable)" [1]
Power / charging connector — what it means The connector the router charges or is powered through. USB-C takes the same charger and cable as most modern phones; micro-USB needs a separate cable.	Micro-USB [1]
Rated power — what it means The rated or maximum power draw from the spec sheet. It sets the load on the socket and the energy use.	4.5 Wless than 4.5 W [1]
Supply voltage — what it means The supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter.	5 V ⎓ 1 A (Micro-USB); charger 100–240 V AC [1]
Batteries or battery — what it means Which cells it takes and how many. A built-in rechargeable battery is stated in the value.	removable, 3.8 V, 1500 mAh [1]

Control and features2

Display — what it means A display on the housing shows signal level, operator, battery charge, connected devices and data used without a phone. Without one, this information is in the app or web interface.	No, indicator lights onlyLED indicators for signal and battery [1]
Buttons	power, reset [1]

Housing and installation2

Dimensions (W × H × D) — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	62 × 108 × 15.6 mm [1]

Delivery, payment and returns

In your home

A reliable connection underpins your smart home.

A fast broadband plan does not fix weak signal through a wall. Several apps do not become one system by themselves. Placement and verified connections matter.

What to check before buying

We clarify the floor area and number of levels, where the provider’s router sits, which rooms matter for work and video, and whether cable can be run. Real speed also depends on your internet plan and the device itself.
