What does gmail want from me?

I tried to create a gmail account from my house. I have a wired connection and a dumb phone. Everything went smoothly until it reached the phone verification part. It got stuck there and told me to try again after a few hours.

I went to an Internet cafe, created another account and used the smartphone of one of the attendants to verify my account. It worked well and I got an account.

I then went back to my house and tried to sign in to the account I'd created. I used the number of another SIM card I have. Again, gmail informed me to try again later. I tried it again a month later, but still the same message.

How can I successfully use a gmail account from my home? Is it a smartphone problem? Because even when I do get one, I'll not use it online until I've taken several measures to harden it. I'm afraid I may still have the same problem.

Gmail is blocking your home IP for too many checks. Just turn on your phone’s mobile data hotspot and verify the account over that network. Use incognito or clear cookies first. Or use Gologin with Proxy.

Maybe you can restart your router to change the IP

You can try reset your mobile and router. Gmail is restricting your ip. Using vpn might work but not sure.

Google’s phone verification can be strict, especially with repeated attempts from the same IP or device. Try using a mobile hotspot or a trusted VPN and a fresh phone number. Also, clear cookies or use incognito mode before verifying.

What browser you use to create accounts?

You need to find whether the problem is with the device or the internet connection use mobile data and find whether it cause this issue

There are two main possibilities. First, the IP address you're using to create the Gmail account may already be blacklisted by Google. Second, the device you're using might have been flagged due to past spammy behavior. You can try switching to a new IP address by restarting your router or turning airplane mode on and off to get a fresh mobile network IP. If the issue is with the IP, this might help you bypass the phone verification step.
However, if you're still facing the same problem, it could mean your device is flagged. In that case, try registering the account from a different device and IP, or simply use your laptop instead.
Another option, especially if you need to create multiple Gmail accounts, is to use an antidetect browser like Multilogin, Hidemyacc, or similar. These browsers simulate clean, separate devices, helping you avoid device-related flags. Still, in most cases, the core issue is often the IP, so if it's important, consider investing in a clean proxy.

You can try with mobile data and new devices. Too many try actually harmful. Thats the case here.
