Review: Nil tech setup and great performance. - I have recently migrated from a DSL internet setup which was becoming increasingly dated and unreliable, a problem of living in a rural area where only one 'phone company has a monopoly on services. I was cautious and did not want to commit financially to a big outlay for an idea that might not work so I purchased this Cudy N300 as a lower cost experimental introduction to cellular internet. I only need to say I am extremely pleased and satisfied with the result. The Cudy N300 was inexpensive, simple to set up and provides excellent performance. I believe I am about a mile from the cellular antenna the Cudy uses but it performs well with no external antenna. I just measured my up/down speeds and presently have 14M download and 7 M upload, this compares with 1.8 and 0.9 with the DSL system. I have seen values as high as 25/18 on other occasions with no other arrangements than positioning the Cudy on an upper floor near a window and roughly pointing it in the direction of the cellular antenna. Originally our family has had cellular service with AT&T with home landlines and internet provided by the "other" company. I have transferred all services to AT&T on their Premier plan so presently we have three cellphones, an Apple watch and two data sim. cards with AT&T who have been amazingly helpful and patient during the complex transition to their service. The two data sim cards are interchangeable in the Cudy, each card has 50Gb of data time so if I run out of data on one card (which may happen near the end of the period) I simply switch the sim card in the Cudy and off we go again. This is not an advertisement for AT&T but it is relevant to the concept of changing to an all cellular service. Our original land line service with internet and add-ons was costing us $104 per month. This service has been terminated. The increase in cost of our cellular service with AT&T, for one cellphone line and two data sim cards, is $45. Not bad since we get improved internet service together with a $60 dollars a month saving. I gave 3 stars for tech support, average, not because it was deficient but I simply did not need it so I can't give a true score. .
Review: Worked perfectly when we needed it most! - I'm not usually one to write reviews, but was blown away at the simplicity and effectiveness of this product and just had to share! I bought this months ago along with a data-only SIM from Google Fi. We live in Florida and you never know when disaster may strike. Strike it did - in the form of Hurricane Ian. The cable for our Xfinity connection is currently laying in our yard. I activated the data sim using my phone, pulled the router out of it's box, inserted the SIM card and said a prayer. Low and behold, it immediately connected - I used the network name and password off the bottom of the box - was online in under a minute. Yeah it's not the world's fastest connection, but I wasn't expecting that and it's perfect for what we need. Couldn't be more pleased - and the rest of the family thinks I'm a genius!

### ⭐⭐⭐⭐ No internet available
*by J***N on October 14, 2025*

There wasn't any internet service available in our area. We purchased the Cudy to leak with our AT&T service to get internet via WIFI. The service work pretty good most of the time. If there were several people trying to use the internet it would slow down. The unit worked well enough for my son to play online games with good speed and quality. The range covered the 2000 square foot home we have without any problems. We had the divice for over 3 years and haven't had and problems. Also, depending on the monthly service agreement you pay will vary as well as your bandwith limits. Overall it did what we needed for a good price until fiber internet was available in our area.
