With Super SIM you can also have access to multiple networks at once. For example, if you’re connected to T-Mobile and move to an area where there isn’t coverage, your device can automatically switch over to AT&T. This gives you redundant connectivity too in case any one network or tower goes down.
Matt, I’m not sure what the spam filter is latching in to, but you may want to try varying your opening line a little bit for each response.
Please, please, for the love of god, please add an "email" verb to the twiml language.
You can make it super restrictive if you need to - like you can only email addresses that you can prove you own ... or something.
All I want is to be able to cc: an email with certain SMS alerts and it takes a sendgrid account and write some functions and validate email @ sendgrid with real names and addresses and on and on and on ... just to send an alert to an email address.
I think what happens is that tower leases in some protected areas can be hard to negotiate, so the cost/benefit ratio gets out of whack for new towers (amongst other issues with power, construction, and RF propagation in remote, mountain areas). Maybe someone with more knowledge can chime in.
In some locations, there just isn't any land to site the tower due to regs (national parks comes to mind, nothing except my Iridium hotspot works in parts of the Smokey Mountains), so there are no providers or a single provider who was able to swing a special case on an existing tower (water tower or similar).
