Hi,

Trying to send SMS to another country gives timeout and ERROR:500. This has been working ok earlier.

Current firmware RUT2XX_R_00.01.14.4

I can send troubleshooting files if someone can take a look.

Hello

Thanks for contacting TELTONIKA | Crowd-support forum. 

Have you tried theses option?

- changing '+' by '00'

- Rebooting the device

- Resetting your router to default factory settings.

- Trying another SIM card while trying to send SMS.

- Reflashing the firmware through bootloader menu

Best Regards
