If you need a SIM to set up a hotspot
This SIM provider is an outstanding solution for simplicity (pun intended) affordability, and support. Needed to set up a hotspot for nanny-cams to monitor my mother-in-law who has dementia. Chose spectrum, and have been thrilled with my decision. Not only was the initial activation a surprising breeze, the subscription options were perfect for my budget. Spectrum recently updated their network which required updating my SIM chip. They sent me a new SIM (free) and transferred my account settings and existing data balance over to the new chip. The process was seamless with virtually no interruption in service; very important factors given the function this provides. Throughout the process, order, shipment, installation, etc, Maria at Spectrum Customer Service, held my hand and answered all my silly questions; often within minutes of my emails! This level of service is becoming increasingly rare these days!! My hats off to Spectrum, as a company, and especially to Maria as an exemplary representative!

Excellent customer service
It took me a few tries, but it was worth it. The customer service rep. did not leave me to dry, she followed up with me until I got to work. Now itโs like I have a giant cell phone in my truck dashboard. I highly recommend Puffin SIM card.

Easy Setup, Useful Web Status Page, and Great Customer Support
This was relatively easy to set up on my Gl.Inet device. Also after I had it set up and needed to pause data to troubleshoot a test device and then restart data service, Maria from customer service was very responsive and helpful.

Highly Recommended if you need Best 5G Network and Wide Coverage Best 5G DATA SIM
I use a BlackVue DR970X-2CH LTE Plus (NA) dashcam that takes a SIM card, and I specifically needed a data-only SIM with wide coverage and a cost-friendly plan. I spent a lot of time researching different SIM providers and networks, and that search ultimately led me to the Spectrum Smart SIM. I've been using it for 6+ months now, and it has been a solid experience. My previous SIM only supported 4G, but Spectrum recently sent me an upgraded SIM that supports 5G, which was a nice improvement. On top of that, their data plans are now more competitive than what I was seeing elsewhere. The best part is the coverage. The 5G SIM works with T-Mobile and AT&T, depending on the area, and it automatically connects to whichever network has the best signal. That has made a noticeable difference for me, especially when driving through remote areas-it's reassuring knowing the SIM will switch to the strongest available network instead of getting stuck on a weaker one like some other providers. The setup was also straightforward. Activation was easy, and the only manual step was entering the APN settings, which took just a minute. After that, it worked right away.If you're using an LTE/5G dashcam and want a reliable data-only SIM with strong coverage and flexible plans, this has been an excellent option for me so far. Customer Support: Excellent Customer Support, Prompt Next Hours email Reply and very helpful, which I've never seen in other Services.

Great customer service and product!
I was looking for a way to purchase internet service as I needed it, rather than pay every month for service that would not be used except for a few weeks out of the year. This is exactly what I was looking for. Our phones have unlimited text and talk so all I needed was service to stream TVs and operate laptops. This data only product is perfect! I'm using the sim card in a NETGEAR Nighthawk M1 4G LTE WiFi Mobile Hotspot (MR1100-100NAS), which I'm also pleased with. The first sim card I received worked, but for some reason I still don't understand it thought we were in Austria and wouldn't stream Hulu for example because it's not offered there and would only stream the Pluto TV offered in Austria. I contacted customer service via their contact form on their site (there doesn't seem to be a phone number) and Maria contacted me within hours. She mailed me a new sim card and it is working great! Mistakes are made all the time in business and life and the difference is in how a company responds and I'm extremely pleased with the quick replies and resolution! Just as an fyi, the data pricing advertised on here with the original card I bought was showing 12GB for 12 months for $60, but the new card they sent me did not offer that pricing. It is 12GB for 12 months for $84. I'm not clear why there was a difference, but it was not a deal breaker for me as this is still going to be less expensive than paying for traditional internet year-round service. I'm also thinking this will be great to use if we lose power for any extended time!

broke after 3months
Was expecting to have to change settings on my camera, put in and started working immediately. the subscription plans are better and cheaper than most other sims. my previous was charging $155 a year that came with my camera... edit I bought a year subscription, after 3 months the sim stopped working, contacted support, they reset sim said sim was fine, I bought a new one from their company, bought another year subscription and I thought it was working fine, support transferred the additional time to the new sim for me which was nice... overall however the sims must just not get the service in my area like the used to because it is still not working... Wasted like $60.. and had to swap over to eiotclub sims that are working great... shame because eiotclub is a lot more expensive for their plans. buyer beware some areas dont have best coverage I suppose... worked originally for 3 months, now it won't.
