Review: SIM Router That Changed Everything - I honestly wish I had upgraded to this SIM card router sooner. We spent two years struggling with our old setup — barely able to use the TV, and if someone was streaming, no one else could get online. Most of the time, my housemates had to sit right next to the router, and even then only two people could connect. Speeds were slow to very slow, and coverage only reached 2–3 rooms. This new SIM card router has been a massive upgrade. It now covers the whole house with high speeds, even in our rural area where signal is usually weak. Setup was easy, and I even managed to change the password — that took a little more effort, but it was still straightforward and impressive. Hardly any issues since, and now everyone can stream or watch TV in their own rooms without a problem. Reliable, fast, and with great coverage — exactly what we needed.
Review: Good 4g alternative to fiber and copper based WiFi options - I live in a third floor flat and was looking for a WiFi solution as my current supplier (full fiber) was unable to supply. The 5g coverage is outside only, so I decided to go for this 4g router as 4g coverage is excellent in this area. I have paired this router with a Smarty unlimited data SIM on a monthly DD payment (currently £20 pcm). My use is to stream TV desertcart fire tv (I have used a cable to the router ), working from home on lap top (multiple screens, browser tabs, Citrix corporate apps), tablet, mobile phone. This product works extremely well, speed is better than the connection in the office and whilst upload speeds are slower than the fiber I had, they are perfectly adequate for my use. My expectations for this products performance have been exceeded. The connection process was easy and my printer (CannonT55350i) and home and work laptops connected with ease, and worked well together, simply putting in the password on the bottom of the router. Coverage is not tested a one bedroom flat. I have it positioned adjacent to an external wall. Good value purchase and a realistic long term replacement to fiber and far better than copper, and with the smarty simm there is freedom from expensive contracts and punitive exit fees.
