To summarize, prepaid is available from providers such as
- Verizon
- Verizon
- T-Mobile
- Virgin Mobile (using the Sprint network)
Verizon has two options:
- 3GB for $60/month ($20/GB)
- 10GB for $90/month ($9/GB)
T-Mobile has several options:
- 1.5GB for $25/month ($16.67/GB)
- 3.5GB for $35/month ($10/GB)
- 5.0GB for $50/month ($10/GB)
Virgin Mobile has two options:
- 2GB for $35/month ($17.50/GB)
- 5GB for $55/month ($11/GB)
Going by a pure dollars per gigabyte metric, the $9/GB is the lowest cost, but it is also the highest usage bucket. IF you think you'd actually use 10GB in a month.
In the 5GB range, it's a choice between Virgin Mobile and T-Mobile.
T-Mobile offers a 3.5GB if you don't think you'd use up 5GB in a month.
Verizon's 3GB for $60/month is the most expensive per GB, followed by Virgin Mobile's 2GB for $35/month.
T-Mobile's 1.5GB for $25/month appears to be targeted at folks that want an inexpensive plan, but it's the third most expensive in the per gigabyte metric.
From a dollars per month perspective,
- for $25 a month, you have T-Mobile for 1.5GB
- for $35 a month, you have a choice between T-Mobile 3.5GB and Virgin Mobile 2GB. Both have nationwide coverage, but, perhaps, maybe the Sprint network behind Virgin would be better. However if you're not roaming much outside major cities, the larger T-Mobile bucket may be your better choice.
I'm not going to provide an opinion on the more expensive plans.
