hi everyone, a friend of mine bought a multi-sim iphone clone from china. i was so amazed at this. as a hobbyist, i want to create my own pc-based multi-sim gsm terminal. so i want to use 4 gsm modules(sim300). one for each gsm-provider here in my country. but my problem is i want to use only one antenna and the four modules share on this antenna. just like the iphone clone of my friend. I am pretty sure that it uses 2 modules but these modules share on just one antenna. can you guys share your thoughts on this? how can i do this? thanks in advance
