50% more data means 7.5 GB of high speed data instead of the usual 5 GB on Straight Talk's $45/month unlimited talk, text and data plan and 15 GB instead of 10 GB on the $55 plan.
The deal is only available in markets that have T-Mobile service. That means the phone runs on the T-Mobile native network, which is probably a deal breaker for most rural users and those who travel overland extensively. If the offer isn't showing up in your zip code try using 94103, which is a San Francisco zip, to see it.
The Alcatel onetouch Pixi Glory LTE only costs $49.99 and as you can expect it has generally entry level specs. It does have a 5.5 inch screen, which is pretty much unheard of at this price. The resolution isn't specified, hopefully it's at least 720x1280 as anything less will look pretty bad on a screen that large. Other specs include Android 5.1 Lollipop, an unnamed 1.1 Ghz quad-core processor, 8GB of memory and 5 MP (with Ffash) main and 2 MP front facing cameras. The RAM isn't specified but based on the other specs it's probably 1 GB. The battery is non-removable but there is a memory card slot.
I haven't been able to find any online reviews of the Alcatel onetouch Pixi Glory, which isn't surprising as the phone is new. I did find a tutorial for the phone and a PDF of it's User Guide online. The user guide has instructions for turning on Wi-Fi Calling and VoLTE although I don't know if either feature actually works on Straight Talk. But WiFi Calling has been reported to work on the Alcatel Pixi Charm, another T-Mobile based TracFone device, so there's a good chance that feature works on the Pixi Glory as well.
Including more data with T-Mobile based phones to compensate for T-Mobile's lesser coverage makes sense. I wonder if Straight Talk will extend it to other T-Mobile based phones and BYOP SIMs. Straight Talk's practice of offering identical plans on all four networks never made must sense to me. I suspect that T-Mobile or Sprint service costs TracFone less than AT&T or Verizon service so why not give customers something extra on those cheaper networks?
