Mifare Classic emulation

I'm trying to emulate MIFARE classic 1k NFC tag but it's not working as expected.
Here is what I'm doing:

proxmark3> hf mf eload dumpNEW

proxmark3> hf mf ecfill A
#db# EMUL FILL SECTORS FINISHED

proxmark3> hf mf sim

#db# Emulator stopped. Tracing: 1  trace length: 185

I tried to detect NFC tag using my smartphone (in the log above). It doesn't detect anything.
Here is an example with ACR122:

Again. No tag detected.
Is there anything I missed? Forum search didn't give my anything useful.
