    • $15 per month if your Dish network customer activate in the app do not use QR code doesn’t work
Set name: $25 Unlimited Plan
I was using AT&T prepaid and I switched to boost mobile when I learned they are using AT&T towers now. I am so pleased I am paying 1/3 of the cost each month and this boost mobile SIM card also will work in my AT&T carrier locked phone. It has full functionality in my carrier locked AT&T phone and also works great in my iPhone iPhone 12. Coverage is great the speed of my download has actually increased from when I was with AT&T wireless directly. I get an average of 125 Mb a second download about 30 to 40 mb per second upload. The SIM cards are compatible with a lot of phones. The only issue I had was when I scanned the QR code on the SIM card pack itself I was brought to a site that wanted the Amazon order number or something in that regards and getting this SIM card activated through the method that says to you by scanning the QR code ended on a webpage with an error. So I downloaded boost Mobile app and was able to activate easily that way. If you have a number you’re wanting ported make sure you port it when you activate your SIM card do not wait several days later to port. You cannot beat this carrier for the value for your money. If your Dish network customer you get the $25 a month package for $15 a month. Awesome value for your money!! ... show more

    • To use Ralphie's moniker, "OH FUDGE"
Set name: $25 Unlimited Plan
This was a headache from the start. I had Amazon Boost support call and port my number from Straight Talk to Boost. Agent stated it was activated and all I had to do was swap the sim cards. Put the new boost sim card in. Immediately the phone gave a message at boot up that said Invalid Sim Card. Network Locked Sim card installed. And guess what, now that the phone wasn't on any network it was essentially a brick. Call support, can't help because guess what. They have to send a one time authentication number to my cell number. Can't get text message because I now have a brick. Entire process sucked. However, Boost agents were very kind, professional and cordial. Now I'm stuck in nowhere land without a phone to use. If I manage to get this thing working I'll let you know how the service itself is. Until then stay away ... show more

    • classic bait and switch. I almost bit.
Set name: $25 Unlimited Plan
I shouldn't even give it a star. It was a colossal disappointment. When I entered the iccid number for the chip for my unlocked smart phone I got an incompatible message. Boost mobile told my phone was compatible a chip they wouldn't send me. Then they offered a locked phone of the same model after I sent them a copy my state id. I PAID for a what I thought was a working sim card, boost mobile representatives refused to make it right without considerable effort on my part. I would think very hard on getting this chip for your unlocked smartphone. ... show more
