Модем Quectel ep06

Привет. Подскажите самую стабильную прошивку для Quectel ep06-е. Спасибо

Hello sir, you need to contact local sales staff and FAE or send an email to support@quectel.com to get Quectel tools, documents and firmware packages.
Thanks and best regards.

I sent request to support@quectel.com also by last week but still no answer yet :
Its only the option to get firmware upgrade?
