Hi guys, would like to ask if there is any choice for proper internet accessibility?

We opened a cafe The Journey and is using Yes 4g. Though the speed is fast, but because of the quota we can only have sustain such speed for 1 week+ only.
Would really want to provide good wifi accessibility for people to hangout, but really out of ideas. Thanks

Thanks. But i am using zoom 4g, which doesnt have the ability to block certain sites. It just broadcast the wifi only..
Willing to pay for service to anyone who can trottle any user's speed to speed that i prefer, if it ever can be done..
