Still not receiving MMS after 1.4 update

Ahhh. In another post on this forum I’ve found the following information:

I understand that you’re trying to edit the APN settings on your Mudita Kompakt, which is a crucial step for getting mobile data and MMS to work correctly.
There are generally two reasons why you might be having trouble: either the ‘add’ option is a bit hidden, or your mobile operator has locked the settings on your SIM card itself. This guide will help you determine which one it is.
Part 1: How to Add a New APN on Your Mudita Kompakt
First, let’s make sure we are looking in the right place. Please follow these steps exactly to add a new APN profile:

Go to Settings: Open the main Settings menu.

Select Network & Internet: Tap on Network & Internet.

Select Mobile network: Tap on Mobile network.

Go to Advanced: Scroll down and tap on Advanced.

Select Access Point Names: Tap on Access Point Names (APNs).

Press the ‘+’ Icon: In the top right corner of the screen, you should see a + symbol. Please tap this to create a new APN profile.

Enter and Save: Fill in the details provided by your carrier and then use the three-dot menu in the corner to Save the new APN. Make sure the newly created APN is selected.
If you were able to press the + icon and add a new APN, your issue should now be resolved! If you could not find the + icon, or if all the fields were greyed out and uneditable, please continue to Part 2.

Part 2: Understanding Carrier-Locked APN Settings

The “Why”: If you followed the steps above but could not add or edit an APN, it is because your mobile operator has intentionally locked these settings at the SIM card level. This is not a fault of your Mudita Kompakt. Carriers sometimes do this for specific types of plans, such as:

Certain prepaid or MVNO plans.

Corporate or business accounts.

SIM cards intended for IoT devices.

What You Would See:** When APNs are locked, you will typically see that the fields are ‘greyed out’ and cannot be tapped, or the + icon to add a new profile is completely missing.

The Solution: Because this is a restriction set by your mobile operator, the only solution is to contact their customer support. You can explain that your device requires custom APN settings and ask if they can either unlock them or switch you to a plan that allows for APN editing.
Alternatively, the issue can be resolved by using a different SIM card from a provider that does not lock APN profiles.
We hope this guide has helped you identify the cause of the issue. To summarize, first, try adding a new APN using the steps in Part 1. If you find the settings are locked, the next step is to speak with your mobile operator. Please let us know if you have any other questions.
