常见问题
Why does the network name shown abroad not match the provider the plan was bought from?+
Because the name shown is the local roaming partner your plan connects through, not the plan provider's own name. The provider agrees terms with a local operator rather than building its own network.
Does the roaming partner affect the actual coverage and speed received?+
Yes, directly. A plan receives exactly the coverage and speed that the roaming partner actually provides in that area — no plan has better signal than the underlying network it connects through.
Can one country have more than one roaming partner?+
Yes. Some countries carry agreements with more than one operator under the same plan, which offsets any single network's weak points, while other countries have only a single roaming partner.
Should it be a concern if the network shown differs from a previous trip?+
Not necessarily, since the agreement between a plan provider and a local operator can change over time. What matters is checking whether the internet actually works, rather than judging from the network name alone.
Can a data plan connecting through a roaming partner receive identity-verification SMS?+
Generally not, since most plans are data-only and carry no number for calls or SMS, even though the roaming partner network itself supports it normally for its own local users. Keep the phone's main SIM enabled alongside it if that SMS still needs to come through.
What should be done if unsure whether the network shown is correct?+
First check whether the internet actually works, then try toggling airplane mode once. If still unsure, message us on LINE at https://lin.ee/skDPoNx or email esimonline.asia@gmail.com with the network name shown and the destination.
