I feel helpless arriving in London? Hurry up and come see me!

Before going to the UK, buy a UK SIM card in your home country or just get a one-month plan. After you get familiar with the UK, you can choose other local operators. After arriving in the UK, most airports have free Wi-Fi, so you can connect to it and let your family know that you have arrived safely. Then, you can rest and plan your route. Generally, apps are divided into domestic and international versions. Except for some software like Google, Apple needs to change to a UK account and Android needs to download Google Store. Then, use Google Maps to check how to get to your apartment, whether it is on campus or off campus. After arriving at the apartment, you need to go to the reception to check in. You need to bring your passport and some other documents. After checking in, you can get your key. After that, you can rest and if your apartment includes bills, you can connect to Wi-Fi and let your parents know your current situation. Then, you can eat something and rest. In the UK, the public transportation is mainly buses, subways, and taxis. But it is not recommended to take the subway. If you just want to experience it, it's okay, but it will definitely refresh your impression of the subway. To get your BRP (British Residence Permit), you can usually get it at the school or post office. For school information and IT registration, pay attention to your mailbox. Generally, it will be notified by email. Finally, the lifestyle in the UK is different from that in China. You will definitely not be used to it at first. You need to pay attention to your mailbox, use Google Maps, and protect yourself. Try not to go out alone at night and go out with friends.
