[4.3.0][4.2.0][4.1.0] German Provider o2-de+ not recognized properly on SIM-Cards

explit · 21 October 2024 00:06

I found manual Solution
The needed files are in /var/lib/ofono
There was neccessary to find the right SIM-Number Folder and place inside this folder a file with the filename cache and following content

[sim]
spn=o2-de

Maybe someone can create a fancy patch for this, @nephros maybe ?

Things like the the X10 triple camera thing notwithstanding, I’d rather not mess with ofono internals.

You can try Custom SIM Names though as a workaround

The change here is absolutely cosmetic.
When the file cache is non existent in
/var/lib/ofono/XXXXXXXXXXXXXXX/
the the SIM-Card Name will be Unknown.

I don’t know if this problem exists with other SIM-Cards other than o2-de,
but it would be cool to extend the SIM-Card Name Patch with this feature.

At the moment, the Patch can provide additional SIM-Card names, but when this small modification is missing, it looks like

SIM1 Unknown | Work

what is not a solution…

Suppose that should be written by this, jolla stuff:

github.com

sailfishos/ofono/blob/master/ofono/src/sim-info.c#L142

      
        
            	if (priv->update_imsi_cache && priv->imsi && priv->imsi[0] &&
            		priv->cached_spn && priv->cached_spn[0]) {
            		gboolean save = FALSE;
            		const char *store = SIM_INFO_STORE;
            		GKeyFile *cache = storage_open(priv->imsi, store);
            		char *spn = g_key_file_get_string(cache, SIM_INFO_STORE_GROUP,
            			SIM_INFO_STORE_SPN, NULL);
            
            
		if (g_strcmp0(priv->cached_spn, spn)) {
            			save = TRUE;
            			g_key_file_set_string(cache, SIM_INFO_STORE_GROUP,
            				SIM_INFO_STORE_SPN, priv->cached_spn);
            		}
            
            
		/*
            		 * Since we are most likely running on flash which
            		 * supports a limited number of writes, don't overwrite
            		 * the file unless something has actually changed.
            		 */
            		if (save) {
            			DBG_(self, "updating " STORAGEDIR "/%s/%s",

Then the question would be why there is no proper spn info for this case there.

It could be the case for the German o2-de+ Network, that MNC of the Network 262-03 is not equal to the MNC on the SIM-Card (262-07). Maybe in this case the spn info is not written. Only my idea.
