  • But no gateway (default route)...odd...

(BTW, you don't have to respond in 2 messages to others, just use one post.)

If this is correct, perhaps you need to set the mode as well.

  • To be clear, your local cell service is actually LTE, correct?
  • If not, what mode is it?

but i read that the mode is not necessary, by default is set to all?

No; and you didn't answer my question(s).

You may need to set the other values too, only your carrier could tell you. I surmise you got the APN information, etc. from your cell phone?

config interface 'wwan'
	option proto 'qmi'
	option device '/dev/cdc-wdm0'
	option apn 'web.ho-mobile.it'
	option auth 'none'
	option modes 'all'

Please edit your message and provide complete output of ifstatus wwan_4.
Ping your DNS as asked earlier and also show ip r output.
There is no need to touch any configuration right now.

complete output of what? i don't see any dns here that was the complete output

root@OpenWrt:~#  ip r
default via 10.24.120.129 dev wwan0  src 10.24.120.128 
10.24.120.0/24 dev wwan0 scope link  src 10.24.120.128 
192.168.1.0/24 dev br-lan scope link  src 192.168.1.1 
root@OpenWrt:~# 

So the OP did edit the output...?

:frowning_face:

From what I read, I saw no DNS or gateway...what's incomplete?

My bad, that would be a gateway.

OK...but no DNS...can you ping 8.8.8.8 now?

no i can't

I guess external resources are not available at the moment and all the traffic is redirected to a captive portal or something like that.
If the same SIM works in the phone I suggest to use the phone to obtain operator's DNS settings. Once they are known, they could be added to OpenWrt manually.

Just in case... will be good to see a result of

uqmi -s -d /dev/cdc-wdm0  --get-current-settings

and

wget -s http://194.185.163.71

Using curl -I is more common for this purpose, but it is not installed by default

i tried another sim card and is working.so why ho is not?

It probably works, but 1st they probably want you to do something on their portal. Please test as I described to be fully confident.
