@leenquin considering it's based on your phone number and it's quite possible to take over someone's phone number (either using a number porting scam, or SS7 hacking), it's definitely a real possibility. It is something a common miscreant can do? Not yet, anyway.
@joeo10 happy to be off the road and out of the blast zone of multiple CPX360 events. Trying to get back to normal…
Now that I'm off the road for a bit, I can return to my usual afternoon Starbucks.
@matigo Prepaid in the US is not nearly as convenient or as cheap as it is in, say, Thailand where I was able to buy a $10 SIM from a Kiosk that included call credit and 3GB of high speed data which expires in a week.
T-Mobile has a travel SIM deal [prepaid-phones.t-mobile.com], which is $30 for 2GB of high speed data for 3 weeks. Don't believe AT&T has a short-term tourist plan.
@matigo LTE can provide adequate speeds if there is backhaul and spectrum to support it.
In the US, they are still clearing away spectrum previously used by television stations that will be repurposed by the mobile operators. Existing phones also don't necessarily support that spectrum.
So, yeah, it's not nearly as fast as it could be.
