Our verdict on each
MobileX
MobileX suits US readers who want a prepaid plan with a low entry price and no contract attached, scoring 9.4 overall. Build Your Own starts at $3.88 on 1 month, and that same monthly rate carries into every later period, so nothing has to be unwound at renewal.
yallo
yallo suits Swiss readers who want a line costing nothing until they use it, on a rolling monthly setup over Sunrise's network with Europe roaming already covered. Entry is CHF 0 a month and the unlimited tier starts at CHF 21.90, and the free plan is the reason to look here first.

Pros and cons
MobileX
Pros
- Build Your Own starts at $3.88 on a plan where the data allowance is set by the customer
- Plans run 1 month, so there is no long term to serve
- Unlimited talk and text plans start at $14.88
Cons
- European roaming is paid, so travel adds cost rather than arriving with the plan
- The seller type is mvno, so service runs over a host network and local coverage needs checking
- Coverage is listed for US, so anyone who needs service across several countries should look wider
yallo
Pros
- yallo starts at CHF 0 a month on a pay-as-you-go basis, so a second line costs nothing until it is used.
- Billing is rolling and prepaid and the plan contract length is 1 month, so a reader can leave without a long notice period.
- Europe roaming is included and the host network is Sunrise, so travel abroad does not require a second provider.
Cons
- On unlimited data yallo ranks 87 of 173, far behind its 1 of 258 showing on entry price.
- yallo is an mvno on the Sunrise network, while getesa and yesss! are listed as a network in their own right.
- Service runs in CH only, so readers based anywhere else need a different brand.
Who each suits
MobileX
Who it suits
- Residents of US who want a prepaid plan with no long contract
- People who want unlimited talk and text from $14.88
- Readers who want an eSIM, rollover data and hotspot sharing on a flexible plan
Who should look elsewhere
- GETESA readers who would rather buy from a network than a mvno
- Lonestar Cell MTN readers who want the network itself rather than a virtual brand
- Travellers who need roaming inside the monthly plan, since European roaming is paid
yallo
Who it suits
- People in Switzerland who want a spare or second line without a contract, starting at CHF 0 a month.
- Travellers from Switzerland who need Europe roaming already included rather than a separate roaming add-on.
- Readers who are happy with pay-as-you-go data but still want eSIM, 5G and WiFi calling on one prepaid plan.
Who should look elsewhere
- People who would rather buy from the carrier itself, since getesa and yesss! are both listed as a network while yallo is an mvno.
- Readers outside CH, where yallo does not run at all, should look at a brand built for their market, such as lonestar-cell-mtn.
- Anyone whose main goal is the lowest unlimited rate, since yallo sits at 87 of 173 on that measure.

Questions about each
MobileX
What is the cheapest MobileX plan?+
Build Your Own starts at $3.88 and you set the data allowance on it yourself. The published reference prices for the plans are monthly and month to month, so that entry figure is the ongoing figure rather than a promotional rate that changes later. A reader comparing a low headline price with a long contract deal is comparing two different structures here, not two stages of one sale.
Does MobileX use contracts or lock-ins?+
No long term is attached. Billing is prepaid and rolling and plans sit at 1 month, the short contract length that flexible mobile deals tend to use. Nothing ties you in for a year, so a reader who wants to change plan or walk away can do so without serving out a term first.
yallo
What does yallo cost at the start?+
The Prepaid plan starts at CHF 0 a month, so opening a Swiss number costs nothing on its own. Data on that plan is pay-as-you-go, meaning you pay for what you use. There is no minimum contract on the prepaid tier, so a line can be opened, used lightly and closed again without a long commitment.
How much is unlimited data on yallo?+
The Swiss Max plan, which carries unlimited data, costs CHF 21.90 a month with no minimum contract. A further unlimited tier costs more than Swiss Max and also comes without a minimum contract, so the rate you renew at is the rate you start at rather than a promotional step up later.
