Verdict

The call

The clearest difference is review sentiment: D at 100% against EG Sim Card's 25%. D also leads on update cadence (every 4 days vs every 2 months). EG Sim Card's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
