Inexplicably fond of tethering, I switched from the standard Straight Talk 5GB/$45 plan to their new 10GB/$55. Needless to say, that still ain't enough. So I'm looking at Metro's unlimited/$60 plan, but have questions... I have a Samsung Galaxy Core Prime SM-820L. It is CDMA, has a SIM card, but I'm not sure if the card really does anything. Metro also sells that phone – can I assume the above specs will match? Metro sells a SIM card for making one's existing phone switch to Metro (child of T-Mobile). Can I further assume that my phone will accept the Metro SIM card; fit physically and connect digitally? Does Metro's unlimited plan really mean unlimited? I usually use around 300MB per day, but can go way past that, depending on what I'm up to. Finally, I use Klink to tether via USB. It works great and Straight Talk doesn't notice or care about it. Can I assume Klink will work the same way when connected via Metro?
