Verdict
The clearest difference is in-app purchases: Termii Authenticator at none against VSim's 6. Termii Authenticator also leads on ads (none vs shown) and update cadence (every 10 days vs every 2 months). VSim's advantage is ratings volume (17K vs 6). On price, device support and iOS requirement there is nothing between them.
