EC25AUFAR06A03M4G — latest firmware request (VoLTE/IMS registration fails on Telstra)
Hi,
Could you please send me the latest firmware for my module?
Current version (AT+QGMR): EC25AUFAR06A03M4G_01.001.01.001
I’m using this on Telstra (Australia, MCC/MNC 505/01) for VoLTE calling. IMS enables but never registers (AT+QCFG="ims" → 1,0), and calls fail with NO CARRIER / AT+CEER: 2,169. All Australian carriers have shut down 2G/3G, so VoLTE is the only voice path.
I’ve confirmed SIM, signal, network registration, correct MBN selection (Telstra-Commercial_VoLTE), and IMS APN/PDN activation are all healthy — this looks like it may need a firmware update to resolve, similar to this related case: EC25AUX VoLTE/IMS registration issue
Thanks in advance.
