EC25-E - IMS not registering on Orange France network - Missing MBN file

IoT Modules LTE Standard Module

Hi,

I have a Quectel EC25-E module (4GDEC25E USB) running firmware EC25EFAR06A21M4G (20.302.20.302) on Ubuntu Linux.

I am trying to send SMS over IMS with an Orange France SIM card. Orange France has migrated to SMS over IMS only (no classic GSM SMS).

Issue:

  • AT+QCFG=“ims” returns 1,0 (IMS enabled but not registered)
  • AT+CMGS fails with error 305
  • AT+CGATT=1 and AT+QIACT=1 work fine, module gets IP address
  • AT+QMBNCFG=“list” shows no Orange France MBN profile

Steps already done:

  • Flashed latest firmware EC25EFAR06A21M4G
  • Set AT+CGSMS=0 (packet domain)
  • Set AT+CGATT=1
  • Activated PDP context with AT+QIACT=1

Could someone please provide the Orange France MBN file compatible with firmware EC25EFAR06A21M4G?

Thank you

Hi,

I wanted to follow up on my previous post as I still haven’t been able to resolve this issue.

To summarize the situation:

  • Module: EC25-E (4GDEC25E USB)
  • Firmware: EC25EFAR06A21M4G (20.302.20.302)
  • OS: Ubuntu Linux
  • SIM: Orange France (SMS over IMS only, no classic GSM SMS)

Current diagnostics:

  • AT+QCFG=“ims” → 1,0 (IMS enabled but NOT registered)
  • AT+CGATT=1 ✓
  • AT+QIACT=1 ✓
  • AT+CGSMS=0 ✓
  • AT+QMBNCFG=“list” → only ROW_Generic_3GPP available, no Orange France profile
  • AT+CMGS fails with error 305

I have already tried:

  • Selecting ROW_Generic_3GPP MBN profile
  • Manually setting APN contexts (AT+CGDCONT=1,“IP”,“orange” and AT+CGDCONT=2,“IP”,“ims”)
  • Disabling auto MBN selection (AT+QMBNCFG=“AutoSel”,0)

The IMS second parameter stays at 0 no matter what I try. I believe the Orange France MBN file is needed for IMS to register properly.

Could anyone provide the Orange France MBN file compatible with firmware EC25EFAR06A21M4G, or suggest another way to get IMS working with Orange France?

Thank you
