The first time I planned a multi-month trip combining a London base with home-country visits in Pakistan and onward to Bangkok, I'd assumed I would buy three separate eSIMs — one for the UK and Europe, one for Pakistan, one for Thailand. The 99esim Diaspora plan covered all three on a single eSIM at less than the cost of two of the country plans I'd budgeted. The trip became one continuous data experience rather than three separate activations.
Why a Diaspora plan exists as a category
The plan name reflects the typical user pattern: travellers who maintain ties across multiple regions. Pakistani diaspora returning home from London. Thai diaspora visiting Bangkok from Berlin. Central Asian diaspora moving between Almaty, Bishkek, and family in the EU. South Pacific or US-based travellers maintaining work and family ties across the Atlantic and Pacific.
These travel patterns don't fit neatly into "Europe regional" or "Asia regional" buckets — they cross multiple regions on a single trip and need one connectivity product that spans the whole pattern. The Diaspora plan covers 49 specific countries chosen to match these patterns: the EU and adjacent European states for the European base, Pakistan and Thailand for South and Southeast Asian roots, Central Asia for the post-Soviet diaspora, Israel and Turkey for Mediterranean ties, the US and New Zealand for the Anglo-Pacific diaspora, plus Tunisia and Kuwait for the broader Arab-world connection.
Most travellers using the Diaspora plan fit one of three shapes: South Asian or Central Asian diaspora returning home from Europe (multi-week or multi-month trips combining a European city base with extended family stays in Pakistan, Kazakhstan, or Kyrgyzstan); Southeast Asian diaspora combining Bangkok or other Thai destinations with a European or US base; and multi-region business travellers in industries (energy, finance, NGO, academia) where the standard travel pattern crosses continents.
What coverage actually looks like across 49 countries
The European core (EU 27, UK, Switzerland, Norway, Iceland, Faroes, Liechtenstein) has 5G across most major metros and continuous 4G across the rest. The Western Balkan additions (Albania, Bosnia, Montenegro, Serbia) have 4G across the major cities and main highways.
The Mediterranean and Middle Eastern additions: Israel has 5G across Tel Aviv and Jerusalem. Turkey has 5G across Istanbul, Ankara, Izmir, and Antalya. Tunisia has 4G across Tunis, Sousse, and the Mediterranean coast. Kuwait has 5G across Kuwait City.
The Eastern European additions: Ukraine has 4G in operational regions (the war has affected coverage in some frontline areas). Moldova has 4G across Chișinău and the central districts.
The Central Asian additions: Kazakhstan has 4G across Almaty, Astana, and the major settled corridors with thinning across the steppe. Kyrgyzstan has 4G across Bishkek and Osh; the Tien Shan mountain regions thin or lose signal.
The South and Southeast Asian additions: Pakistan has 4G across Karachi, Lahore, Islamabad, and the major cities; Northern Areas (Hunza, Skardu) have variable coverage. Thailand has 5G across Bangkok, Chiang Mai, Phuket, and the major tourist hubs with continuous 4G across most settled regions.
The Pacific additions: New Zealand has 5G across Auckland, Wellington, Christchurch, and continuous 4G across most populated areas.
The North American addition: the US has 5G across all major metros and continuous 4G everywhere.
How the major eSIM providers compare on this multi-region scope
The Diaspora plan is unusual in the global eSIM market. Competitors do not sell a directly-equivalent product covering this specific multi-region footprint.
99esim Diaspora covers the 49 specific countries at €3.49 / 1 GB / 7 days. Custom-plan flexibility scales up to 50 GB / 60 days for extended-stay travellers. Group-eSIM benefit covers up to four devices.
Airalo Discover Global covers approximately 165 countries (truly global) at $8.50 entry. Significantly broader scope but meaningfully higher per-GB pricing. Use Discover Global if your trip needs Africa, Latin America, or East Asia in addition to Diaspora's footprint.
Holafly does not offer a directly-equivalent multi-region plan in the tracked set. Holafly's regional plans are split per region (Europe, Asia, Middle East, North America, etc.) and don't combine into a single Europe-plus-Asia-plus-Pacific product matching the Diaspora pattern.
Nomad Global covers approximately 123 countries at $12 / 1 GB / 7 days. Broader than Diaspora but at higher per-GB cost. Use Nomad Global if multi-continent flexibility matters more than the specific country list.
Ubigi does not offer a directly-equivalent multi-region plan in the tracked set; coverage requires combining Ubigi's Europe and country plans.
The matrix below spells out the per-axis shape. For trips whose itinerary fits within 99esim's specific 49-country list, the Diaspora plan is the cheapest option for that exact scope. For trips needing destinations outside the list (Africa, Latin America, China, Japan, India, the Philippines, Indonesia), a global product from Airalo or Nomad is the right comparison.
Install timing: when to set it up
Install the eSIM the night before you fly, or during the first layover. The QR code generates immediately after payment; scan it with your phone's eSIM settings; the profile installs but doesn't activate until it first sees a tower in any covered country. The eSIM works whether you start the trip in London, Almaty, Lahore, or Bangkok.
iOS 17.4+ devices can install directly from a provider's app without scanning a QR code, on providers that support it. Android users still scan a QR code, which takes thirty seconds.
Who should pick what
A multi-month diaspora visit pattern (Europe base plus Pakistan, Thailand, or Central Asia home visits) benefits from the larger 99esim tiers (20-50 GB / 40-60 days) that match multi-month diaspora travel patterns. Custom-validity flexibility suits this use case well.
A multi-region overland or rail trip combining Europe with Central Asia and Southeast Asia (Berlin to Bangkok via Tashkent and Almaty) fits a 10-20 GB plan because daily navigation and translation use across multiple regions adds up.
A combined Europe + US trip (e.g. London + New York + LA + Paris) wants either the Diaspora plan (which includes both Europe and the US) or stacked country plans depending on duration. Diaspora wins for longer multi-week patterns.
A truly-global trip including Africa, Latin America, China, Japan, India, or major destinations outside the 49-country list wants Airalo Discover Global or Nomad Global rather than Diaspora.
A short Europe-only trip is better served by 99esim's standard Europe plan (38 countries at €1.99) — the multi-region scope of Diaspora is wasted economy.
A Europe + Russia or Europe + Philippines trip wants the Europe + Balkan plan instead of Diaspora — those specific countries are covered by Europe + Balkan but not by Diaspora.
A heavy streamer use case is unusual on the multi-region scope; Holafly's per-region unlimited plans don't combine cleanly across this footprint.
A group of three or more travelling together, particularly a multi-region business delegation or family diaspora visit, benefits from 99esim's group eSIM, which covers up to four devices on one purchase. None of the tracked competitors offer that product today.
A note on overlap with other 99esim regional plans
99esim's regional product line includes both Diaspora and Europe + Balkan plans, both at 49 countries and the same entry tier of €3.49. The country mixes overlap substantially but differ on specific destinations. The choice between the two is best made by checking the exact country list against your itinerary rather than by name. If your trip includes Russia, North Macedonia, Andorra, or the Philippines but not Croatia, Montenegro, Sweden, or Slovakia, choose Europe + Balkan. If your trip is the inverse, choose Diaspora. If your trip includes destinations from both lists, you may need either to stack two plans or to upgrade to a global product. Both 99esim regional plans share the same group-eSIM benefit and custom-validity flexibility; the differentiation is purely the country list.
