Zebronics Zeb WR3004G Review

Quick Summary

The Zeb WR3004G from Zebronics is a compact SIM-based Wi-Fi 6 router for places where there is no broadband line, or where a backup connection is needed. You slot in a Nano SIM, plug in the power and share the mobile connection over Wi-Fi or a LAN cable. Its strength is that idea of a simple, portable network; its compromise is that the Wi-Fi is single-band 2.4 GHz and there is just one 10/100 Ethernet port. The brand's store lists it at ₹5,999.

Design & Build Quality

The WR3004G is small and light at 146 g, measuring about 15.1 × 5 × 22.1 cm with the antennas raised. That makes it easy to put on a shelf, a window ledge or a shop counter, where a SIM signal is usually best. There is only a reset button on the outside, so there is nothing to learn physically; the SIM slot, the Ethernet port and a charging port are the only connections. It runs on a power adaptor supplied in the box, together with a LAN cable and a QR code guide.

The antenna layout is worth noting: one for Wi-Fi and two for LTE. Having two cellular antennas is a sensible choice for a router whose job is to hold a mobile signal, as it helps with reception in weaker coverage.

Wi-Fi and Mobile Performance

The WR3004G supports Wi-Fi 6 (802.11ax), but only on the 2.4 GHz band. The official page quotes a Wi-Fi signal rate of 286 Mbps for sending and 229 Mbps for receiving. In practice, the real limit is the mobile connection behind it: the listed LTE bands are 850, 900, 1800, 2100 and 2400 MHz, and although the brand says the router is compatible with 4G and 5G SIM cards, the bands it lists are LTE bands. Treat it as a 4G LTE router and do not expect 5G speeds from it.

For home use, a shared 4G plan for phones, a TV stick and a laptop is exactly the sort of job it fits. The 2.4 GHz-only Wi-Fi reaches farther than 5 GHz through walls, which is an advantage in a house with thick walls, but it is more exposed to interference from neighbours' networks.

Ports & Connectivity

There is a single RJ45 10/100M port that can switch between LAN and WAN. This is clever but limiting. As a SIM router it works as a LAN port for a desktop, a CCTV recorder or a printer. If you want to use a wired broadband line as the WAN and share it over Wi-Fi, the same port does that job, but then you cannot also plug in a wired device. For a household with several wired devices, a router with more ports or a separate switch will be needed.

Features Assessment

The useful features are the SIM slot, the auto-switching LAN/WAN port and WPA2-PSK security. Basic network controls are present: port forwarding, port filtering, URL filtering, UPnP and a DMZ. There is no guest network, parental control or mobile app listed on the official page, so management is likely to be through a basic web page. For a plug-and-play router of this size and price band, that is acceptable, but it is not a feature-rich product.

Ease of Use

Setup is meant to be simple: insert a Nano SIM, power on and follow the QR code guide in the box. There is almost no hardware to configure, and the lack of extra ports and bands also means there is less to get wrong. Firmware updates and advanced management are not described on the official page.

Value for Money

At ₹5,999 on the brand's own store, the WR3004G is priced above what its hardware suggests: it has a single 100 Mbps port and 2.4 GHz-only Wi-Fi. Third-party listings on shopping sites show it at a much lower price, but those come from small sellers and are not treated as main-seller prices here, so check the seller, the warranty and the return terms before buying from one. At a lower price it makes more sense; at the brand's list price it is a convenience purchase for people who truly need a SIM-based router.

Who Should Buy It?

People who need a simple way to share a 4G SIM connection, such as small shops, rented rooms, holiday homes, temporary offices and homes that want a backup for broadband outages.

Who Should Consider Alternatives?

Buyers who want 5G speeds, dual-band Wi-Fi, Gigabit ports or several wired connections should look at a more capable 4G/5G router or a regular dual-band router, since this model's single-band Wi-Fi and one 100 Mbps port will feel restrictive.
