You bought data before a trip, installed the profile in a couple of minutes and then found the “Personal Hotspot” row dimmed, unresponsive or missing from Settings at the moment your laptop needed it. Nothing is usually wrong with your account. On most travel plans the embedded SIM (eSIM) profile has reached the phone without the tethering half of its Access Point Name (APN) configuration, so the operating system quietly hides a control it cannot deliver.
Adding that missing entry by hand settles the majority of cases in under 2 minutes. You type the tethering APN your provider publishes, save it, turn the line off and on again, then test with a real laptop rather than trusting the status bar icon. A carrier help centre run by Sure in Guernsey identifies exactly this cause, missing hotspot APN data behind a greyed-out control. The same logic applies to travel profiles.
Everything below stays on that single problem. Qrispy’s help centre already explains what an APN is and how hotspot sharing works on an eSIM, so this guide covers the causes of a dimmed control, the exact menu paths on both platforms, the rules that override anything you type plus the order to work through them in.
Why personal hotspot greyed out eSIM happens
Sharing your connection is not simply the same data session handed onwards over Wi-Fi. On most mobile networks, tethered traffic runs through its own gateway profile so the operator can identify it, count it or price it separately from the browsing you do on the handset. That second gateway profile is the tethering APN. A complete carrier profile installs 2 sets of details at once: one for the phone itself and one for anything connected behind it.
Travel profiles arrive through the same provisioning path as any other carrier profile, yet the tethering entry is the piece most likely to land empty. Apple responds by dimming “Personal Hotspot” so you cannot switch on something the network would refuse. Android behaves less predictably: the “Hotspot & tethering” screen usually still opens, then the switch flips itself back off after a second or your laptop joins a network that carries no traffic at all.
What your phone checks first
Before that control becomes usable, your handset runs 4 quiet checks: a tethering APN on the active data line, a signal that sharing is permitted on this subscription, no management policy forbidding it and data left to share. Fail one check and the switch greys out, disappears or refuses to stay on.
Check the simple things first
Roughly half of these reports are settled before anyone opens an APN screen, so work through the quick items in order.
- Confirm the travel eSIM is actually selected as your mobile data line rather than sitting installed but idle.
- Turn Data Roaming on for the travel line, since travel profiles connect as a visiting network almost everywhere.
- Check the plan still has an allowance left or that your wallet balance sits above zero.
- Restart the handset once, which reloads the carrier profile from scratch.
- Install any pending operating system update, then accept a carrier settings prompt if one appears.
Check the row again after each step rather than running all 5 at once.
Add the tethering APN on iPhone
Apple only exposes APN editing when the installed profile permits it, which most travel profiles do. The screen sits 3 levels deep, under the plan itself rather than the general network settings. It holds a separate block for sharing.
- Open Settings, then “Mobile Data” or “Cellular”.
- Tap your travel plan in the “SIMs” list, then tap “Mobile Data Network” or “Cellular Data Network”.
- Scroll past the browsing fields to the “Personal Hotspot” heading near the bottom of that screen.
- Type the APN value your provider publishes into the “APN” field, exactly as it is written.
- Leave “Username” and “Password” empty unless your provider supplies both of them.
- Go back, switch Airplane Mode on for 10 seconds, then switch it off again.
Personal Hotspot should now open normally. Never guess at an APN value or reuse one from another provider, because a wrong entry produces the most confusing outcome of all: a hotspot that broadcasts happily while no page ever loads on the connected device.
Label differences by region
Apple changes the wording by locale rather than the behaviour. Devices set to the United Kingdom, Ireland, Australia or most of Europe show “Mobile Data” and “Mobile Data Network”. Devices set to the United States or Canada show “Cellular” and “Cellular Data Network”. The APN value never follows the language of your phone. Type it in lower case exactly as published, with no translation and no stray spaces at either end.
Should both labels be absent, the profile you installed has locked APN editing. That is a provider-side decision rather than a fault on your handset, so the next move is a support conversation.
Add the tethering APN on Android
Android exposes the same fields with far more variation between manufacturers. On a Pixel, open Settings, then “Network & internet”, then “SIMs”, pick the travel line and open “Access Point Names”. On a Samsung handset, open Settings, then “Connections”, then “Mobile networks” and “Access point names”. Other brands sit between those 2 paths, under the mobile network section.
- Open the “Access Point Names” list for the travel line rather than for your home line.
- Tap the plus icon or “Add” to create a fresh entry instead of editing an existing one.
- Put a recognisable label in “Name”, then the published value in “APN”.
- Set “APN type” so that it includes dun, short for dial-up networking, which marks an entry as usable for tethering.
- Leave the protocol fields alone unless your provider tells you otherwise.
- Save from the 3 dot menu, then select your new entry using its radio button.
Networks differ on structure. Some expect one combined entry typed as default,dun while others want a second entry carrying dun on its own. If the first arrangement fails, save the other and test again. Where the whole list is dimmed, editing is locked on that device, so try Bluetooth tethering or a Universal Serial Bus (USB) cable next.
When the row disappears completely
A dimmed row and a missing row point at different problems. Dimmed usually means the profile is present but incomplete, which is the APN case above. Missing usually means you are looking at the wrong line.
On a dual SIM iPhone, “Personal Hotspot” appears once at the top level of Settings and follows whichever line carries mobile data. Switch the data line to your travel plan and the row comes back. If it stays hidden, the profile carries no tethering entitlement, which is worth raising with the provider before buying more data.
Plan rules that block tethering
Some subscriptions genuinely exclude sharing. Prepaid tariffs in certain markets treat tethering as a paid add-on, business tariffs sometimes cap the shared volume and heavily discounted consumer plans occasionally strip it out. No APN edit overrides a network-side rule, so read what your plan includes before spending another 20 minutes in Settings.
Qrispy takes the simpler route. Unlimited personal hotspot is included on every plan, sharing draws from the same balance or allowance as the phone itself, so 1 gigabyte (GB) used by a laptop is 1 GB from your plan. On an Unlimited Data Plan there is no cap on how much you share, although fair use or temporary speed management can apply during very heavy usage or congestion.
Work phones and management profiles
Company-owned handsets are the second common cause. Mobile device management (MDM) disables tethering as a policy, which greys the control rather than removing it. No manual configuration brings it back.
On iPhone, open Settings, then “General”, then the “VPN & Device Management” list, where VPN stands for virtual private network. Any profile shown there came from an employer, a school or an operator. Android equivalents live inside a work profile. Either way, the answer is a message to whoever administers the device rather than a factory reset.
Other causes worth ruling out
With the APN correct and no policy in the way, a few smaller causes remain.
- Low Data Mode active on the travel line, which holds back background traffic and makes a working hotspot look dead.
- A virtual private network app on the phone that captures traffic before it reaches the shared connection.
- A hotspot running only on the 5 gigahertz (GHz) band, which older laptops and some cameras cannot see.
- An eSIM installed but never reselected as the data line after a restart or a software update.
- A handset locked to a single carrier, which blocks the travel profile long before hotspot becomes relevant.
Check for a locked phone early when the eSIM has never worked properly. Qrispy’s device compatibility checker settles that question in seconds.
A quick order of operations
Use this as triage when you have 10 minutes in an airport.
| What you see | Most likely cause | First thing to try |
|---|---|---|
| Row is dimmed and will not open | Tethering APN missing from the profile | Enter the published APN by hand on the travel line |
| Row is not in Settings at all | Wrong data line selected or no entitlement | Switch the mobile data line to the travel plan |
| Switch turns itself off after a second | No data left or roaming disabled | Check the balance then Data Roaming |
| Laptop connects but nothing loads | Tethering APN present but incorrect | Re-check the spelling and the APN type |
| Everything dimmed on a work phone | Device management restriction | Ask whoever administers the handset |
Where Qrispy fits on hotspot
Before replacing a plan that seems broken, enter the verified Qrispy tethering APN and run one honest test: connect a laptop, load a page that is not cached and watch the data counter move. That separates a configuration problem from a coverage problem in under a minute.
Qrispy runs on a single One eSIM that you install once and keep, with coverage across 210+ countries and regions. Unlimited personal hotspot is included on all plans. Top up the Global Wallet and pay as you go, with credits that never expire. You can also stack a Fixed Plan on the same eSIM for a single country. The line carries data only, so keep your primary SIM active for calls and one-time passcodes while Qrispy handles the data.
One quirk is worth knowing. Smart IP Routing sends traffic out through the nearest Qrispy Point of Presence (PoP), which lowers latency but can make your connection appear to sit in another country. Coverage and data usage are unaffected, though a geo-restricted streaming service may notice, on the phone and on anything sharing the hotspot.
Frequently asked questions
Why is my Personal Hotspot greyed out?
The most common reason on a travel plan is a missing tethering APN in the installed profile. Your phone hides a control it cannot honour, so the row is dimmed rather than broken. Plan restrictions, a device management policy or an unselected data line explain almost all remaining cases.
Do I need a separate tethering APN?
Yes in most cases on iPhone, where the “Personal Hotspot” block sits below the browsing fields and is filled in separately. On Android it depends on the network. Some expect one combined entry that includes dun in the APN type, while others want a second entry dedicated to tethering alone.
Can I edit APN settings on iPhone?
No. The installed carrier profile decides whether the APN screen appears, so the option is present on many travel plans but absent on others. When “Mobile Data Network” or “Cellular Data Network” is missing entirely, editing has been locked at the provider level and support is the only route forward.
Does hotspot use more data than browsing?
Yes, usually by a wide margin. A laptop downloads full desktop pages, syncs cloud folders in the background and installs updates without asking, none of which a phone does on mobile data. Pause automatic updates and cloud sync on the connected device before you share a metered allowance.
Will hotspot work without Data Roaming on?
No, not on a travel eSIM. That profile connects to a visiting network in almost every country, so turning Data Roaming off cuts the data session that sharing depends on. Switch it on for the travel line while leaving it off for your home SIM to avoid an unexpected bill.
Can I tether over USB instead?
Yes, though a cable works best as a test. Wired and Bluetooth tethering usually rely on the same permission from the network, so all 3 methods often fail together. When a cable works while Wi-Fi does not, the problem sits in the wireless settings on your phone rather than in the APN.
