TL;DR: Most RoameSIM plans set APN automatically. If you need a manual APN, use globaldata for both the line/APN name and the APN field, unless your order email shows a different value. Wrong APNs cause “connected but no data.”
RoameSIM APN values
- Name / label (line name):
globaldata - APN:
globaldata
Leave username and password empty unless your order email says otherwise. Always prefer the apn_value on your tracking page or delivery email if it differs from globaldata.
When to touch APN
- You have signal / LTE but no internet.
- Your RoameSIM email or track page shows an APN value (often globaldata).
- Support asked you to add a specific APN.
Fix data roaming and the correct mobile-data line first. APN is usually step two.
Android: add an APN
- Settings → Network & internet → SIMs / Mobile network.
- Select the RoameSIM eSIM → Access Point Names.
- Add APN.
- Name:
globaldata - APN:
globaldata - Save → select that APN → restart.
Samsung path is often Settings → Connections → Mobile networks → Access Point Names. Full device tips: eSIM not working on Samsung.
iPhone: APN
Many iPhones hide APN for carrier profiles. If Mobile Data Network appears under the eSIM line, enter globaldata in the Cellular Data APN field (and matching name/label if shown). Otherwise rely on automatic settings and fix roaming/line selection first. See eSIM not working on iPhone.
Common mistakes
- Copying a random APN like “internet” from forums instead of
globaldata. - Editing the home SIM APN instead of the travel eSIM.
- Skipping data roaming checks.

Frequently Asked Questions
What APN should I use for RoameSIM?
When a manual APN is required, set both the APN name (label) and the APN value to globaldata, unless your order email shows a different apn_value.
Do travel eSIMs need a manual APN?
Often the profile configures APN automatically. Add globaldata manually if you have signal but no data, or if support asks you to.
Where do I find my RoameSIM APN?
Check the delivery email and order tracking page (apn_value). If it is blank or says globaldata, use globaldata for Name and APN.
Can the wrong APN block internet?
Yes. Delete custom APNs you added by mistake. Prefer globaldata for RoameSIM travel plans unless your order lists another value.
Is APN the same as Data Roaming?
No. Roaming allows foreign networks; APN defines how data sessions are created.
