Sim card

[Ina1]

Hi, my updated SIM card, I was put to phone ( iPhone 11pro) from august month in EU country-Lithuania, because old SIM card was old model and not worked well( but with old SIM card I had my plan in all countries). Until now with new SIM card I don't have internet, I can't call, I can't text, nothing. I checked this new SIM card with different phone Samsung and iPhone 7, this card doesn't work, I checked all the settings, everything is ok. But interesting , when I turn off my phone and turn on , then I have about 3min. 3G connection, but only few min. and everything disappear. So ,I still in Lithuania and will be here 1 more month. Will be nice if you could help me, because I need this phone number and my plan in the EU countries. it’s very important for me. Thanks.
