I had to go into the settings and manually correct APN etc. as the auto-selected options were all wrong. I also changed it to 4G only mode which caused it to switch from band 1 to band 20, which on O2 should theoretically be better. After these tweaks speeds were a lot higher, topping out at around 20Mbits/s which is reasonable compared to what I’ve gotten from other devices in the building. I then switched over to Vodafone and it seemed to do a better job of auto-detecting settings. It has been peaking at more like 35Mbits/s which is about half of what my iPhone gets - pretty good seeing as that phone cost many times the price of this device and is supposedly Cat18. More importantly, it seems quite stable so far The firmware interface is quite basic and sometimes a bit glitchy, but it feels surprisingly snappy So I would recommend this product providing you already have some experience setting up mobile devices and aren’t expecting blazing fast speeds at this price. Obviously there are more expensive options available that should be faster Review: Ultimately disappointed and no use - I selected this because of the nano SIM slot for 4g, Wifi and the 2 ethernet ports, the latter allowed me to drop in line to an existing wired connection. It has a good (but limited) UI, no connection debug log and appears to be android based. However when it came to using the 3G/4G functionality it was useless for me 1) will not work with SIM from sub providers like Lebara where an MCC/MNC code is needed to work with the main provider. The UI does not support this, it is possible the tech support could provide a json file to work round this they provide an EMail for such but I didnt test 2) using a Vodafone sim self configured to an old APN and sort of worked, but if I used this profile or the one from the Vodafone website for the APN it only connected at 3G (the USB dongles I tested at the same time had no problem to get 4G using the same SIM) = slow 3) found a LycaMobile SIM (EE) worked too but was also very slow 4) it kept dropping the 3G/4G link regardless of if I set preferred or not. I may have just been unlucky with this unit but as I was disappointed and spent a day trying to make it work as expected enough was enough and gave up.

Ultimately disappointed and no use ### ⭐⭐⭐⭐⭐ Small in size, but capable of getting good running speeds *by R***Q on 10 June 2026* We bought this router for the caravan, or to be correct, my daughter/son-in-law's caravan, where a previously purchased router, bought elsewhere had failed miserably. Taking it out of the box, the first thing I noticed was the size, considerably small than I had expected, but yah if it works, no problem; and it does have the double antenna. I was hoping that the connection would be as described, as simple as plug in and use; I believe a few tweeks were necessary, but thankfully I wasn't the one doing this. I won't go in to details because basically what I was told made little sense to me; but I can tell you that with a little fiddling about with the setting, we were soon up and running. Now we are running the speeds are great, probably better than we expected to be honest; and the fact that it is so much smaller is a plus really in a more compact area. The signal/speed is a great improvement on what we'd been getting before, in this rather remote area. I would advise anyone buying this router to have a little knowledge of technical issues which can be solved easily if you know what you are doing; otherwise it is a great bit of kit for a very reasonable price. ## Frequently Bought Together - Tenda Router 4G SIM 4G03 Pro - Mobile WiFi Router 3G/4G Wireless Band 2.4 GHz 300Mpbs, LTE Cat4 150Mpbs, Fast Ethernet LAN/WAN Port, 2 * 4dBi External Antenna, NANO SIM Card, Plug and Play - SMARTY 5G/4G Data Sim, Data Deals Unlimited Calls and Texts, NO Credit Checks, NO Contract, Pay when you Activate SIM - SMARTY Unlimited Data only SIM. 1 month plan, No contract, EU Roaming --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/567032348-tenda-4g-lte-wifi-router-4g03-pro-mobile-router-unlocked](https://www.desertcart.hr/products/567032348-tenda-4g-lte-wifi-router-4g03-pro-mobile-router-unlocked) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-20*
