Does the P40 support eSIM?
The P40 is what decides whether a travel eSIM installs, not the Huawei name on the box. Storage, radio and market variant all change from one model to the next, so every figure below was checked on this model.

What the P40 does with a travel eSIM
The P40 is a phone, so the travel profile is a data line and your existing line stays the voice line. Calls and texts to your usual number keep arriving while Orbislo carries the browsing.
Installing writes the profile. Nothing is spent until it attaches to a network at the destination, so an install three weeks early costs exactly the same as one at the gate. Do it at home, on wifi, while you still have a connection to fix anything.
Storage and active lines
The P40 holds 1 profiles, which is at the low end of everything we have checked. Delete the dead profiles from old trips before you install, or the sheet will simply refuse.
Active is how many lines run at the same time, and on the P40 that is 1. Storage is how many profiles sit on the device waiting, and that is the number that runs out without warning.
Each destination's line installs in one tap from the Orbislo app, and while it is valid every refill lands on that same line. Most of Europe runs on a single line, so a trip through several neighbouring countries takes one slot rather than one per country.
- Home line: calls and texts, so bank codes still arrive on your usual number.
- Orbislo line: mobile data, with roaming switched on.
- Automatic data switching: off, or the phone borrows the expensive line in a tunnel.
5G on the P40, and where it will not appear
The P40 has a 5G radio and the travel profile uses it. Where a partner network runs 5G, you get 5G, on the same profile and at no extra cost.
88 of our 197 destinations are 4G only on the networks we buy from. On those the icon reads LTE whatever the handset can do, and no setting changes it.
Speed belongs to the network rather than to the profile.
What goes wrong on the P40, and the fix
Data roaming has to be switched on for this line. Your profile is issued outside the country you are standing in, so the device treats every attachment as roaming. Leave it off and the P40 finds a network and then refuses to use it.
If the profile will not download at all, the order refunds automatically inside 60 seconds, with no ticket. Install again from the same order, because the profile is reissued to your account rather than lost.
On this device the sequence is Settings, Network and internet, SIMs, the Orbislo line, Roaming on. Then set Orbislo as the SIM for mobile data and turn off automatic data switching.
- No service on the Orbislo line: roaming is off on that line.
- Connected but nothing loads: mobile data still points at the home line.
- Works, then stops after an hour: automatic data switching moved you back.
- Still searching: airplane mode on for 20 seconds, off, then restart.
Your SIM tray, and tethering
Your physical SIM stays exactly where it is. Adding an eSIM does not touch the tray, does not wipe the card and does not need it taken out. Remove it and you lose your own number, which is the opposite of the point.
Tethering is included on every Orbislo plan at no extra charge. The P40 can share the travel data with a laptop, a tablet or a watch, and nothing behind the hotspot needs a profile of its own.
What an Orbislo plan does once it is installed
Data never expires. A gigabyte you do not use in Lisbon is still there in Bangkok next year, metered plans have no throttle, and every customer gets 100 MB of free rescue data once a month on the line in use when the balance runs out. Unlimited runs full speed to 2 GB a day and then 1 Mbps.
One balance pays in all 197 destinations, and most of Europe runs on a single line, so a rail trip through three neighbouring countries is one install and one balance rather than three of each. Refills arrive on the line you already have, with no new plan or expiry date. Where a destination has more than one partner network, the line can move between them without you touching a setting.
How to install a travel eSIM on the P40
- Open the Orbislo app and tap Install
- Confirm the eSIM download prompt
- Settings, Network and internet, SIMs, select Orbislo
- Turn on Roaming and set Orbislo as the SIM for mobile data
Data roaming sounds like it will cost you money. On the Orbislo line it cannot, because it is how that line reaches partner networks abroad and there is no charge beyond the data you already bought.
The P40 at a glance

| 5G on partner networks | Yes, where the network runs it |
| Physical SIM tray | Yes, and it keeps working |

Stored is how many profiles the device keeps. Active is how many run at the same time. Checked on this model rather than assumed from the brand.
P40 eSIM questions
Does the P40 support eSIM?
How many eSIMs can the P40 hold?
Will I lose my own number?
Do I have to turn roaming on?
Can I install before I fly?
Does tethering work on the P40?
Pick the destination, then install its line in one tap
Take the metered wallet for maps and messaging, because the balance never expires. Take unlimited if you tether a laptop or stream, and read the 2 GB a day figure before you do.
The P40 by market
- Single SIM model: The single SIM version of the HUAWEI P40 has one nano-SIM slot and an eSIM, and also takes a Huawei NM memory card. This is the only P40 version on which a travel eSIM can be used.
- Dual SIM model: The dual SIM version of the HUAWEI P40 takes two nano-SIM cards and has no eSIM. Travellers with this version need a physical SIM card at their destination.
Networks on the P40
- On the HUAWEI P40, only the primary SIM connects to 5G, on bands n1, n3, n28, n38, n41, n77, n78 and n79. The secondary SIM is limited to 4G, 3G and 2G.
- The P40 primary SIM covers LTE bands 1, 2, 3, 4, 5, 6, 7, 8, 9, 12, 17, 18, 19, 20, 26, 28 and 32. The secondary SIM has the same list without band 32.
- Huawei notes that eSIM on the P40 needs a mobile plan from a carrier that supports it and that availability varies by country and carrier, so a travel eSIM provider has to support this model.
Worth knowing about the P40
- Huawei's specifications list EMUI 10.1, based on Android 10, as the operating system the HUAWEI P40 launched with.
