Instructions for specific clients
With MyEtherWallet (MEW) or MyCrypto (MC), token balances are displayed on the right-hand side if you scroll down. There should be an option to add tokens. It is the same process with the Ledger or Trezor if you are using these via MEW or MC.
The following are examples of some other Ethereum clients that should allow you to receive ERC20 tokens. The list is not exhaustive and it is not guaranteed that the information is up-to-date. It is important to do your own research on these matters. This is also not an endorsement, if in doubt check with the developers.
