I just switched to Visible $40/month for unlimited everything. Their data is limited to 5 Mb/s and you can only connect one device at a time to the hotspot. You can only have one cell phone on an account. If you want two or more phones you will need multiple accounts, each costing $40. If you can live with these limitations, it's a great bargain.
Porting my number was a simple process, BUT you better hope you never have a problem because their customer support is a joke. The only means of contacting them is by chat session or text message. You can not call them.
You need a WiFi connection to get started. I activated my phone on Tuesday and all seemed to go well until I discovered I had talk and text but no internet. I was using my old phone for my internet connection and since that phone now has no service, I no longer have internet and there is no information on how to text message them. I head for my library to get a WiFi connection and start a chat session. After about an hour of trying various things with no resolution, it is deemed that I have a serious problem and my case will be
"expedited" and someone will contact me in
3 to 5 days. Yes that's days not hours. It is now Saturday morning and I have been to the library three times to check status of my ticket. Each time I get the same run-around stating they are working on my problem. During my last chat session on Thursday I asked if a factory reset might be an option. After several chat sessions and text messages no one had suggested a factory reset. I did a reset and all is now working. I haven't told them that I fixed the problem. It is now Saturday morning and have not heard from them yet.
To get around the one device connection to the hotspot, I'm using a GL.iNet GL-AR150 Mini Travel Router. You can pick one up on Amazon for $26.

So, if you intend to keep your existing phone number, DO NOT port it over to start with. Once everything is working then port your number.
