The cheapest and most reliable cell phone provider is Visible wireless as well as Mint Mobile, Total Wireless and even redpocket.
Visible Wireless starts at $25.00 to $35.00 per month, Mint Mobile runs from $15.00 per month and total Wireless runs from $25.00 per month and most commonly use T Mobile or Verizon Towers.
Straight Talk is also a cheap and reliable cellphone provider that uses Verizon Towers with great coverage.
Lycamobile is also cheap and I pay $19.95 per month for unlimited talk and text, although Lycamobile uses AT&T towers and they don't have as great of coverage.
RedPocket uses Verizon towers from what I've heard and I'm thinking of switching to redpocket cellular soon.
According to my cellphone with Lycamobile the cellphone towers that Lycamobile uses are AT&T cell phone towers.
AT&T cellphone coverage is not all that great in all areas, so make sure you have good AT&T Coverage before switching to Lycamobile.
Lycamobile is a good cell phone provider as I have lycamobile and it has worked just fine.
I have the lycamobile $19.95 a month plan and have had it for a few months now after I switched from Straight Talk to save a bit of money.
Although lycamobile is cheaper than Straight Talk or Verizon for example, Lycamobile cell phone coverage is not as great as Straight Talk or Verizon and where I'm at I cannot get a good signal inside my house, but when outside it works just fine.
In a larger town where I go shopping the Lycamobile coverage is just fine in that location as well.
I mainly switched due to finances, but loved Straight Talks wide coverage as I never had any issues with getting a signal in my house with Straight Talk.
I would recommend Lycamobile if you have good AT&T cell phone coverage in your area as Lycamobile uses AT&T towers, which is what is showing on my cellphone.
They sent the lycamobile card through FedEx quickly and it was also easy to port the number over, although I had to contact Straight Talk customer service to have them give me a code to help me get my number ported from Straight Talk to Lycamobile.
However it went pretty quickly and pretty easy.
