The T-Mobile 55+ plan is $70/month (total include tax, etc.) for 2 phones. You cannot have more than 2 phones or any kind of 3rd line like a MiFi device.
With the 2 phones you can use either/both phones as a hotspot with unlimited data as well but it is at 3G speed. For an additional $10/month you can add 10Gb of 4G Hot Spot data to 1 phone or $10/month on each phone if you want 20Gb. For $25/month you can add unlimited 4G data Hot Spot to 1 phone. So your options are $70/month (3G hotspot unlimited). $80/month (10Gb 4G hotspot) $90/month (20Gb 4G hotspot with 10Gb per phone). $95/month (unlimited 4G hotspot). What ever the cost of new phones would be additional. We got 2 new Samsung S9 with a 2 for 1 deal so we pay another $30/month for the 2 new phones or a total of $100/month.
