We apologize for any inconvenience this may have caused.
Some carriers' 4G networks may support fewer frequency bands. You can try switching to a SIM card from another carrier to see if your internet speed improves.
As for making calls directly with the SIM card, this feature has been disabled due to network access restrictions. If you need to make calls or send text messages, you can install a dialer app and a messaging app on your own to make calls and send/receive text messages.

То есть если я установлю гугл звонилку приложение то можно будет совершать звонки с сим-карты которая установлена в dudu7?

DUDU-Meng
hello,
Thank you for your answer.
I have the GSM card from Vodafone Romania and it works perfectly both in tablets and in the old Ownice C500+ audio system, so it is not from Vodafone. Regarding the "dialer app" application, where can I find it?
You said: " this feature has been disabled due to network access Thank you

Maybe you're right—it's not a Vodafone issue, but rather a result of DUDU7's incomplete support for the frequency bands used by Vodafone. This is because each carrier uses different frequency bands.

DUDU-Meng I think that when you sell such a nice equipment in European countries, where Vodafone is one of the most important players on the Telephony and data market, you should have all the frequencies set. TOMORROW I'll try with the DIGI subscription card, let's see if it does the same and come back. How do I activate the possibility of receiving SMS and calling directly without Bluetooth and another phone? I have Skoda octavia 3 2018 and canbus is form RISE decoder, P/N G-RZ-VW58 2509 and SW: V004 12 12 04 -HS HW VW-GN-010B 25029 Although it is connected via the canbus adapter, not all information is read. I understand that an ODBII adapter would be useful. Which version of ODB from mekede is recommended so that it can be fully accepted by dudu7?

DUDU-Meng i need help , please

hello,
with DIGI ROMANIA, internet is more better....i have 40 mb...and is ok . i tested in my garage, not on the road....

but... i have new problem...
I made a big mistake. while trying various settings with the gsm modem, I blocked the unit and it no longer saw the modem on the internet side. I reset the unit but I didn't realize that there were 2 places where it could be reset. I chose from the darker picture .... and after the reset I lost most of the preinstalled applications that it came with. now it looks very ugly .... and .... there was also a reset in the android settings at system / rest options and the password 3368. but I didn't know. what can I do now?

How can I assist you today?
Are you experiencing an issue where some settings haven’t reverted to their default values after a system reset?
If so, you can use the cleanup files and boot files on a USB drive to perform the upgrade, which will effectively restore the device to its factory default settings.

DUDU-Meng Ok. Thank you. Please explain to me what I need to do to not "spoil" it any further.
I saved the iron on my computer. Do I unzip it and put it on the stick? WHAT do I do next? What do I do before running what's on the stick?
Thank you

rodanny

DUDU-Meng you say: you can use the cleanup files and boot files on a USB drive to perform the upgrade, which will effectively restore the device to its factory default settings.
How can find this file?

Hi everyone!
Can someone tell me which GSM networks and frequency bands the DUDU7 supports? I can’t find any detailed specifications anywhere, which makes the product look unreliable to me. And it really matters whether it’s worth buying these at 3× the price of earlier quality units just because the user interface is different.
In my opinion it’s unrealistically expensive, at least compared to European salaries.
I won’t build a career from installing these at this price, even though I install about three units per week.
And I won’t even buy one for myself to test, because I don’t think it’s any better than what I’m using now.

Mtxaudio8 The LTE frequency bands supported in each country are different. You can tell me your area and I will help you check the supported frequency bands.
GSM is a 2G network and it should not be able to provide high-quality network speeds now, and the software does not support call functions. I think I can ignore it.

DUDU-Meng In Hungary all service providers have shut down 2G and 3G, and what still works is 4G — but mostly only for data — and LTE.
5G is a complete mess in this country, and I don’t even want to use it. Hungary Mobile Network Frequency Bands (2026)

Notes for Android Head Unit / Modem Developers
3G (UMTS) has been completely shut down in Hungary by all mobile operators.
LTE Band 20 (800 MHz) remains the most important band for nationwide coverage, especially in rural areas.
LTE/NR Band 28 (700 MHz) is becoming increasingly important for both LTE and 5G coverage.
Band 32 (1500 MHz SDL) is Supplemental Downlink only and cannot operate as a standalone LTE band. It is used exclusively for Carrier Aggregation.
Band n78 (3600 MHz) provides the highest available 5G throughput.
One Hungary primarily uses NSA (Non-Standalone) 5G with DSS, while Telekom Hungary and Yettel Hungary also operate Standalone (SA) 5G in parts of their networks.
Since 2026, Telekom's 2G service has been provided through Yettel's radio access network, so devices should not assume an independent Telekom GSM infrastructure.
Carrier Aggregation (CA) is widely deployed by all three operators. Devices supporting 3CA/4CA will achieve significantly better LTE performance.
For automotive Android head units and LTE modems used in Hungary, support for B1 + B3 + B7 + B8 + B20 + B28 + B32 + B38 (LTE) and n1 + n28 + n78 (5G) is strongly recommended for maximum compatibility.
