Quectel ec25-au vs ec25-aux

Hi, I was wondering the difference between EC25-AU and AUX version I understand that AU is 256 MB and AUX is 128MB. I use them in a WE826-T2 router from Zhibotong.

Can someone explain me the difference of using 128MB or 256MB in this kind of module? There are any process that only works with 256MB? Any APP that needs a 256 MB Module?

Thanks!
Gabriel

Hello sir, thanks for your question
EC25-AU and EC25-AUX module Band2 does not support diversity reception. You can choose a specific model according to the region or operator.
