PUMPKIN CAR STEREO SUPPORT CENTER

I bought the AE0273B DoppelDIN Android 8 with 4+32GB.

Then i got the Pumpkin 3G Dongle USB Stick Surfstick.
From T-Mobile Germany i got a second WDCMA SIM card and disabled the PIN.
Put it in the Srufstick and into one of the both USB ports and rebootet the System.

But i dont get any internet connection.
Is there any Tool you provide or recommend for analyzing why its not working.

I confirmed the SIM Standard with T-Mobile.
Its a NanoSIM with adapter to standard SIM format
Pin is disalbled
Internet is working smoothly up to LTE in a smartphone

Any thought?

2.if it doesn't help , i suggest you try to reset the unit by using a stick to click the reset button/hole on the panel .Sometimes ,Multiple insertions the 3G dongle would be helpful .
More query, please tell me your order number or ebay buyer id.
Regards

After disconnect the USB Stick and connect it again i now see the Triangle Icon and a message "Kein Dienst" (no service).
The SIM Card is normal telephony&data SIM Card. Does it need to be a special Data Card?
The network is strong in that area.

Hi, you can contact the pumpkin customer service or write to support@autopumpkin.com for more help .
Before that , sorry that i don't know T mobile well . But please notice, out unit only support sim card with WCDMA format. so you can try to contact the customer service in T mobile to confirm whether your sim card support WCDMA internet .
Regards

As i Wort in my first post i already confirmed with Tmobile it is a WCDMA
