I’m going to Vietnam for 3 weeks should I buy this T-Mobile international plan for $50 or is it cheaper to get a ESIM at the airport when I arrive over there? I don’t need phone calls or texts I just need data

tmobile service is usable but not good. I use it only for the first day to call Grab. the next day I go to local provider to get esim, $20 u get unlimited data for a month with very high speed
I was hesitantbabout getting an esim since I have never tried one before. They work great, I got ine from Nomad, no complaints
Get an esim plan before you go. I just got back. Tmobile works over there, but it’s better to have the esim.
Get a local sim(not from the airport) it’s like $15/mo, last time I was there anyways.
Use an International Esim app. NEVER buy an Esim or Sim card at the airport…NEVER. Airalo is a better good app.
HCM has loads of places to buy Sims,I paid around 10$ ,30 days,15 GB per day
If you need esim or Sim card. You have to purchase at the air port. You can’t buy anywhere else.
Just buy the Viettel eSIM on GetYourGuide
eSIM in vn..way cheaper!
Get Airalo app before landing then buy eSIM on Airalo for $10 for 2 weeks.
