Which Aliexpress store is selling original parts?

IoT Modules LTE-A Module

I want to ask if this shop is legit and confirmed to be selling genuine parts:

https://jinyushi.aliexpress.com/store/1890072

Thanks!

This shop is an agency that sells modules from multiple manufacturers and you can consult or ask for a certificate of authorization

Thanks @herbert.pan-Q. Could you provide me some stores on AliExpress that you are sure they have certificates of authorization with Quectel?

Thanks!

I’m sorry that I can’t provide relevant materials. There is no problem in buying from agents in general

Oh, I see. What about stores in general, not Aliexpress only? Do you have a list of approved ones aside Digikey and similar to that?

One last thing is it possible to confirm if something is truly original once getting the module itself? Like S/N check on website?

Thanks @herbert.pan-Q!
