What is the aloSIM travel eSIM?
aloSIM is the bargain-bin travel eSIM. Tiny 1GB starter packs from £2.50, a $3 sign-up credit, and pay-in-GBP pricing make it the cheapest way for a UK traveller to dip a toe into travel eSIMs.
The app is no-frills but works. You'll find aloSIM consistently among the cheapest per-MB rates on short trips, and the small starter packs mean you don't have to overspend. The flip side: coverage isn't as deep as Airalo and you may need to top up more often on longer trips.

aloSIM eSIM — FAQs
Is the aloSIM eSIM compatible with my phone?
aloSIM works on any eSIM-capable handset, including iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. If your phone supports dual SIM with one physical and one eSIM, you can keep your UK number active alongside it.
How much data do I really need on a aloSIM plan?
For typical holiday use — maps, messaging, social, the odd video — 1GB lasts most people 3–4 days. Heavy streaming or hotspotting your laptop can burn through that in an evening, so size up if you plan to work or stream on the go.
Can I keep WhatsApp on my UK number while using aloSIM?
Yes. WhatsApp, iMessage and calls stay tied to your UK SIM. Only mobile data is routed through the aloSIM eSIM, so friends and family reach you the same way as at home.
The verdict
aloSIM wins on price for a weekend city break. Combine the $3 sign-up credit with a 1GB starter pack and you can land in most countries online for under £2. For two-week holidays, look at Saily or Nomad instead.
