Use of EC25-A in India with Twilio Simcard


We have received Quectel EC25 Mini PCle 4G/LTE Module (EC25 - A) along with ordered Raspberry Pi 4G/LTE Cellular Modem Kit. We have also received Twilio Simcard along with it.
We want to use this kit in India and plan to use similar setup in China and Japan. It will be great if you could answer the following queries:

  1. Can we use (EC25 - A) along with Twilio Sim Card in India? If yes, can this set-up work in any other geography since the sim is international. Twilio sim is international. Is this understanding correct?

  2. Is 3G/4G/LTE Base HAT compatible with all the EC25 flavors (including the EC25 modules for Japan and China).

  3. We couldn’t find EC25 module for China. Will EG25-G work in China?

  4. The project development/testing is going to happen in India, China and Japan primarily. Can we go for global EG25-G module for India, China and Japan? The scope will be expanded for worldwide when we go into production. Can we use EG25-G for any country?

Thanks and regards
