Why this router is interesting

CUDY N300 solves a classic problem: you need Wi-Fi, but you don’t have anywhere to plug in a cable. Just insert a nano SIM card with data, and the router creates a wireless network. No complicated setup, no technician needed. It’s a straightforward solution for cottages, caravans, gardens, temporary operations, or as a backup for a fixed connection at home.

While CUDY as a brand isn’t among the most well-known, it has built a solid reputation in the affordable router category over the past few years. On Alza, this model is one of the best-selling – over 500 units sold and a return rate under 1% speak for themselves.

Speed and connection: what to expect from it

The router supports 4G LTE Cat. 4 with a maximum download speed of up to 150 Mb/s. In practice, the real speed will depend on coverage and the operator, but for casual browsing, video streaming, or email, it’s more than sufficient in most locations. The Wi-Fi network operates on the 2.4 GHz frequency with a transfer speed of up to 300 Mb/s (Wi-Fi 4 standard).

There are also two Ethernet ports (10/100 Mb/s) – one can be used as WAN for connecting fixed internet, the other as LAN for a wired connection to a computer, printer, or TV. An interesting feature is WAN failover: if you have fixed internet at home and a SIM card in the router, the router automatically switches to mobile data in case of a main line outage. For homes or offices where an outage is inconvenient, this can be a practical bonus.

Practical aspects: dimensions, security, management

Dimensions of 11.8 × 8 × 2.75 cm make it a truly compact device – you can easily throw it in a backpack or hide it behind a TV. Two non-removable antennas ensure decent Wi-Fi signal coverage, which is also confirmed by users in reviews.

In terms of security, the router supports WPA3. It also features a built-in VPN server and client (PPTP, L2TP) – useful for secure remote connection to a corporate network or for data protection in public places. Management is done via a web interface or the mobile application Cudy App, which allows for basic settings and traffic monitoring.

What users say

On Alza, the CUDY N300 has a rating of 4.7 out of 5 from 13 reviews, with 92% of customers recommending the product. Users most often praise its compact size, ease of setup, and the fact that the router works almost immediately after inserting a SIM card. Several reviews explicitly recommend it for business trips and places without fixed internet.

However, there are important caveats you should be aware of. One user reports that the router did not work with a Vodafone SIM card. Another describes problems with newer 5G SIM cards that exclusively use IPv6 – in such a case, some websites may only function partially. If you have a SIM from a smaller or specific operator, it’s worth checking compatibility beforehand.

A small tip from reviews: if you have a PIN code enabled on your SIM card, the router will not connect. Just disable the PIN on your phone before inserting it into the router, and everything will work without issues.

Verdict: who it’s worth it for

The CUDY N300 is a simple and inexpensive way to get Wi-Fi connectivity anywhere you have a mobile signal. For 849 Kč, you get an LTE router with VPN, WAN failover, and decent security – that’s hard to beat in this price category. If you’re looking for an undemanding solution for a cottage, garden, caravan, or as a backup for home internet, it’s a reasonable choice.

On the other hand, if you need 5GHz Wi-Fi, speeds above 150 Mb/s, or plan to connect a larger number of devices in a more demanding environment, opt for a more powerful model. And if you have a SIM exclusively with IPv6 (some tariffs), verify beforehand whether the router will suit your needs.
