Samsung A3 - Reunited with Lost Phone. Sent remote delete command - safe to proceed?

[Billywizz]

Hi. I (stupidly) lost my Samsung A3 last week on the bus, and due to a good samaritan, it was luckily handed in. On the day I lost the phone, I sent a 'Delete All Command' to the phone via Google, just in case someone had taken the phone and decided to plaster the interent with images of my face. Not a pleasant thought. Today, I have been happily reunited with my phone. The memory card has been deleted, as expected, and the phone, I beleive, will have been 'Factory Reset.' Is it safe now to take my SIM out of my old phone and put it back into the Samsung? I want to make sure, just in case there is a chance the SIM could be compromised when I turn the phone on. Thanks in advance.

SIM will be fine.
I'd factory reset it again, insert SIM and set it up normally.
