Ubigi describes itself as “a global mobile data service” for phones, tablets, laptops and connected cars, backed by Transatel and NTT. It publishes no phone number, no calling plan and no bundled eSIM with a number. Numero eSIM sells all three: numbers in 39 countries, 19 calling plans, and a full eSIM with data, minutes and a real number in 188 countries.
Ubigi is a carrier-backed data operation, and data is all it sells. Its homepage names destinations without a total count, no price, no unlimited tier and no hotspot policy, and nothing on the site gives you a number, a calling plan or a line people can reach. For data alone that may be fine. For anything that involves being reachable, Ubigi has no product and Numero eSIM has three.
Can you get a phone number with Ubigi?
No. There is no number product on Ubigi's site. Numero eSIM sells numbers in 39 countries from $3.99 a month, with toll-free lines in eight and a choice of US area code.
Can a Ubigi eSIM make calls or receive texts?
Not on anything Ubigi publishes: no calls, no SMS, no bundled line. Numero eSIM's full eSIM carries data, calling minutes and a real number in 188 countries and 2 regions, from €16.00 for 20 GB over 30 days.
Can you see the price and the coverage before you buy?
Ubigi's homepage names USA, Europe, Japan, Canada, Brazil, Thailand and Africa without a count or a price. Numero eSIM publishes 181 countries and 7 regions for its data eSIM, the unlimited list of 14 countries plus Europe, the fair-use policy, and the price of every plan.
Ubigi is the travel-data brand of Transatel, an NTT company, and also supplies connected cars and business fleets. The table compares it across all four Numero eSIM product lines; Ubigi competes in one of them.

Ubigi is a Transatel brand, Transatel is owned by NTT, and that shows in who it sells to: travellers, businesses, and the in-car connectivity of BMW, Land Rover, Toyota, Jeep and others. It does not publish much: no destination count, no price, no unlimited tier, no hotspot policy. Every one of those is on Numero eSIM's country pages.
Numero eSIM sells numbers in 39 countries from $3.99 a month, a full eSIM with data, minutes and a real number in 188 countries from €16.00, and 19 calling plans. If a bank, a client or a hotel needs to reach you while you travel, those are the products that answer.
Ubigi's advantage is its infrastructure. An MVNO with an NTT parent and factory relationships with carmakers has a stronger basis for a network-quality claim than a marketplace has. That matters for data, and if data is all you need it is a fair reason to choose Ubigi.
Data in 170 countries with a free, ad-supported tier; no number and no calling plan. Numero eSIM is for the trips where free data is not the whole requirement.
Data in “200+ destinations” from £2.99; its own page says the eSIMs are data-only and do not replace your number. Numero eSIM's full eSIM replaces the number too.
Data in “150+ countries” on lifetime bundles with no expiry, plus hotspot devices, and no phone number. Numero eSIM adds a number the traveller can be reached on.
