I recently bought an Airtel Dlink Universal Mifi and the bonus Airtel SIM doesn't browse, the line has 30GB bonus data on it, I even activated another 1GB data, the SIM doesn't just browse, my reception is great, I even receive 5G signal on it. I've called customer care several times, they couldn't resolve the issue, I Keep getting texts that it has been resolved whereas it hasn't been resolved. Don't know what to do, whether this SIM is defective, I'm not sure.
