What is the right module LTE + for my country Uruguay?

Greetings to all!
I am needing help since I cannot find a solution well, I am from Uruguay and I have tried some modules including Sierra and SIMCOM and I have not been able to make them work with carrier aggregation well. Now I want try quectel
Since in my country the largest operator can do any type of combination in B1 B2 B3 B4 B7 B28 AND B66

I need a module it to be able to do CARRIER AGREGATRION and here the operators work in FDD-LTE IN B1 B2 B3 B4 B7 B28 B66
But the combination could be essentially

  • B2 + B2
  • B2 + B28
  • B28 + B28


  • B1 + B1 / B3 / B4 / B7 / B28 /66
  • B3 + B3 / B4 / B7 / B28 /66
  • B4 + B4 / B7 / B28 /66
  • B7 + B28 /66
  • B28 + B28 /66
  • B66 + B66

(Of all these combinations the most used are b4 + b4 , b4 + b28 and b28 + b28)

Do you know any module that can work well doing this carrier aggregation and that works well with The rooter project firmware?

Thanks for your query in Quectel forums.
I suggest you learn about our EG12 module. I will provide you with the EG12 module specification first. The specification has detailed information. Please refer to the EG12 specification to see if it meets your needs,EG12 specification connection:https://www.quectel.com/wp-content/uploads/2021/03/Quectel_EG12_LTE-A_Specification_V1.0.pdf.
