This is strange. I've just added some debugging code to print what it thinks your number is at that point, so you can verify whether your number is at least what you expect.

If you aren't comfortable listing private information like your subscriber country in public, you can contact me privately at nt8r@protonmail.com.

I will email you the debug info

~anteater 2 years ago

I never received an e-mail, but I did think more about this. Does your number or area code begin with a 0? It's possible vgmms' handling of leading zeroes is incorrect.

~ccf100 2 years ago

My area code is +1 (337)

After compiling commit ffaf37f6d60738e1c10c3cec2a8e40962087518b, Now it returns:

I replaced my number with #'s, leaving the area code intact

~anteater 2 years ago

I haven't gotten around to vgmms maintenance in quite some time, but now that I look at your follow-up, the problem is clear: the number as returned from the modem has no country code! We currently obtain the default country for parsing other numbers from the user's number, but in this case we'll need to have a further fallback source of the information. A user could specify a default country in settings, or there may be a locale-based way to default things.

~ccf100: Are you using ofono or ModemManager?
