eSIM vs 漫游
漫游很方便，但运营商常按天收取5–15美元且流量有限。旅行eSIM一周的费用往往只是其中一小部分。
Roaming: pros and cons
- Pro: one tap, same phone number for everything
- Pro: billed to your existing account
- Con: often $5–15/day with daily caps
- Con: speed throttled after fair-use limit
- Con: may not work for calling U.S. toll-free numbers
Travel eSIM: pros and cons
- Pro: fixed price upfront — often $5–25 for a week of data
- Pro: buy before you travel, activate on landing
- Pro: no contract with your home carrier
- Con: requires eSIM-compatible phone
- Con: usually data-only — voice stays on primary SIM

常见问题
- Is eSIM always cheaper than roaming?
- For trips longer than 2–3 days, prepaid eSIM is usually cheaper than daily roaming passes. Compare your carrier's international day pass to a 5–10 GB eSIM plan.
- Can I use both roaming and eSIM?
- Yes. Keep roaming off on your home line and use the eSIM line for data only to avoid double charges.
