Reliable network, worth every penny
After my Viettel SIM from the airport expired, I made the mistake of buying an eSIM from vietnamesim.com (operated by Gigago) — overpriced, poor coverage, and hotspot completely disabled on their “unlimited” plan. Couldn’t take it anymore after 5 days and went to a physical Viettel store to get a new SIM. Staff were genuinely helpful and the difference was night and day — strong signal everywhere, hotspot works perfectly. Should have just renewed with Viettel from the start.
