TRX and USDT on TRC20 both live on the Tron network, and Tron addresses all start with a capital T. That makes it easy to mix them up. In Enugu or anywhere else, the safest habit is to treat each coin separately.
Copy the TRX address for TRX
In Snapiro, open TRX and copy the address shown there. Do not reuse the address you copied for USDT, even though it looks similar. Each coin screen in the app shows the address to use for that coin.
Then sell
Send on the Tron network, wait a few seconds for it to confirm, and check the naira amount before you accept. Spend it on an EEDC token or data, or withdraw to your bank.
