@felmue Thanks for letting me know. Too time consuming using U137 to go any further trying to get Google map with SMS. Maybe another day.
Easier to just use GPS V2 module M003-V2 and hot spot in vehicle with some email or BOT code which works great.
I did use this GPS V2 module to send GPS data to Adafruit IO mapping and included a IFTTT trigger on AIO that would SMS map of current location with Google voice command.
Also, used this module with core2 to email location map every X seconds.
Anyway, I appreciate your posting, letting me know about this limitation.
