That's quite strange, CMGR response should have an intermediate response =

prefixed by +CMGR: prior to the OK.  Your modem is just weird ;)

What the stock AT modem driver does is reads the message and deletes it rig=
ht =

away.  Somehow your modem says 'sure' to the read request without actually =

reading the message.  Maybe the firmware is just too slow or oFono is too f=
ast, =

or maybe this modem needs extra special magic.
