SIM is activated but Internet does not work

Hello! The SIM is activated yesterday, but I see "Log in to network" message and Internet does not work.

Yesterday I bought two SIM cards (La Poste Mobile) - for myself and my daughter. The cards were activated at the time of purchase. My daughter's Internet works, but mine doesn't. Today the whole day passed, and the Internet still did not work. I tried to insert her SIM card into my phone, the Internet appeared. But as soon as I insert my SIM card, I see the message "Log in to network".

Today I went to the La Poste Mobile office, where I bought a SIM card. They replaced my card, but I still have the same problem with the Internet. All other La Poste Mobile SIM cards works, the only problem is with the my SIM card.
