I dont know much about tron supported wallets but I only used trustwallet when using tron and never failed me to do some transactions. Got chance to use imtoken too but I think only once, also got good grief on using tron blockchain. But there are lots of new wallets I think. But based on experience, I could only recommend trustwallet for smooth transaction.
Did the wallet automatically take care of the energy and bandwidth that JeromeTash mentioned in his reply as soon as you deposited some tron to it or did you have to do something on your end?
Most of wallets that are recommended above are closed source, so they are safe for now, but no one knows what will happen in the future, so if you do not plan to invest large sums or for long periods, they are fairly good.
you can also try ----->

Unstoppable doesn't support tron or USDT over the tron network.
I have nothing else to add to the list already posted above. I just want to ask about those problematic wallets. Can you name at least one or two of them? Surely you still remember. Perhaps it's one of those custodial wallet and exchange like freewallet? There have been many complaints and testimonials of frozen funds.
The complaints I heard were about TronLink which is the network's official wallet I think.
