SubWallet does support XCM (cross-chain) transfer. Below is an example of XCM transfer with SubWallet mobile:
Step 1: Click the Send button on your home screen.
Step 2: In the Send section, please choose your sending account, input the receiving account address, and the chain you want to transfer from and to. Then click Continue.

If you start from a single-account mode, the wallet would automatically fill in the from account section with the address of the account you are currently in. You would not have to manually select a sending account.
To see if you are in the All accounts mode or a single-account mode, please look at the account name on top of the home screen:
