I can reproduce this on an HE910 I just started testing. Basically,
the ofono cellular service never reappears to connman after connman
disconnects it.

# connmanctl technologies
/net/connman/technology/cellular
 Name = Cellular
 Type = cellular
 Powered = True
 Connected = False
 Tethering = False
/net/connman/technology/ethernet
 Name = Wired
 Type = ethernet
 Powered = True
 Connected = False
 Tethering = False
# connmanctl services
*AR Wired                ethernet_001122edb058_cable
*A  T-Mobile             cellular_310260008772362_context1
# connmanctl disable ethernet
Disabled ethernet
# macb f0028000.ethernet eth0: link down
# connmanctl services
*AR T-Mobile             cellular_310260008772362_context1
# connmanctl enable ethernet
IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
Enabled ethernet
# macb f0028000.ethernet eth0: link up (100/Full)
IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
# connmanctl services
*AR Wired                ethernet_001122edb058_cable
#

The cellular service will never reappear.

Contexts for that modem still appear when when listing them via dbus:
dbus-send --system --print-reply --dest=org.ofono /he910_0
org.ofono.ConnectionManager.GetContexts


method return sender=:1.36 -> dest=:1.48 reply_serial=2
  array [
     struct {
        object path "/he910_0/context1"
        array [
           dict entry(
              string "Name"
              variant                   string "LTE"
           )
           dict entry(
              string "Active"
              variant                   boolean false
           )
           dict entry(

              variant                   string "internet"
           )

Manually trying to activate that context fails:
# dbus-send --system --print-reply --dest=org.ofono /he910_0/context1 org.ofono.
ConnectionContext.SetProperty string:Active variant:boolean:true
Error org.ofono.Error.NotAttached: GPRS is not attached


Thanks,

Dear Sir,

We are using CONNMAN/OFONO for wireless communication and network management.

Whenever the connman daemon switches from cellular to wifi automatically, ofonod removes the ppp0 interface.
On the oterhway round the ofono daemon is not doing the addition of the ppp0 interface.

I have been manually activating the context for get it right.

I am using HE910 modem with ofono version 1.16.

Regards,
Ram
