I am soon going to cancel my (originally $25) Kickstarter plan since T Mobile is going to add $5 a line now that the 4 year period of no price increases has come to an end.
They did me a favor actually since I was using very little data so will be perfectly fine replacing the line with something costing $10 or less. Just hadn't gotten round to it since it was nice to have unlimited everything for those occasions (travel, home Internet going down / hotspot needed).
I was going to go with Tello but their additional data charges are expensive, they no longer have unlimited slow data, and I don't want to be renewing early every month to rollover unused data / minutes or get a new plan in case I need more.
