Ahamo Sim Card Activation

Hey everyone, I’m a language student and I finally registered my address to my residence card. Then I went to a docomo store to get ahamo SIM card. The process took some time, but everything went well.When he gave me the SIM card, he told me that I need to activate the SIM card from the web site and it is easy. But they said they could do this for me and and would charge me Â¥3000. I don’t know Japanese so well but since they said it is easy. I said okay I can do it myself. But after that, he asked me to change my phone language to Japanese. Then he picked up my phone and inserted the SIM card. Restarted the phone. Did the APN settings. And I saw him going to do ahamo website. Unfortunately, he didn’t tell me what he did. But I can receive and send messages, I can call people and get called. And I can use my Mobile data.

So my question is, how can I be sure that my SIM card and ahamo plan activated?

(I have a Samsung Galaxy S21 5G and I choosed the 20 GB ahamo plan)

(When I use mobile data I cannot use 5G it is 4.5G do I need to configure a setting to activate 5G?)

  1. Foreign Samsung S21 doesn’t support docomo 5G bands, or lacks proper configuration for them or something like that.
