The worst phone service company I have ever had
This is the worst phone service provider I have ever had. They advertise that it is possible to order a prepaid card with eSIM, but it is not. They say that it is free to switch from physical SIM to eSIM, but it is not. Instead, the system tries to charge me 40 CHF for the privilege and prevents the switch.
Do not use this provider.
Abusive behaviour
One month ago, I was threatened with a 100 CHF fine for not having returned my Wi-Fi modem, which I did return. Back then, I requested my chat transcripts, because they contained the proof of their confirmation of reception of my modem. After multiple emails, I am still waiting. Furthermore, an employee from Packli Punkt sent Yallo an email confirming that they did sign the reception of my modem when I sent it out. After more than 20 emails, I am still waiting for the Yallo "expert committee" to analyze my situation.
One star is more than they deserve for…
One star is more than they deserve for their technical support. I had been a happy yallo customer until last month, when my home internet stopped working. I created multiple support tickets through the chatbot, but nothing was resolved. Calling customer support costs CHF 1.50 per call, and I ended up calling three times in one month. Every time, I was told that my request had been forwarded to the technical team and that they would call me back. Guess what? It's been over a month, and I still haven't received any support or a single callback. They offered no alternative solution and showed no urgency in resolving the issue. This has been an absolutely terrible customer service experience. After waiting for more than a month, I've completely lost confidence in yallo. I would not recommend them to anyone.

I am in the US and so cannot call their "free-toll number" to change my subscription. Every time I start a chat to change it they just tell me all operators are busy. Then I send an email and they tell me to contact them via chat. To add insult to injury in my contract is says explicitly that after the initial period no extra fees will be charged for changing policy and now they want to give me a fee for chaning to another yallo plan!
Extremely time consuming and frustrating. I am willing to provide informations in case someone wanta to sue them.
Yallo did not honor the conditions that were promised to me
Yallo did not honor the conditions that were promised to me
I have been a Yallo customer for several years, but my recent experience has been extremely disappointing.
Background
I had a mobile subscription that included calls to destinations such as the USA and Canada at no additional cost. The subscription was originally under my partner's name, and I wanted to transfer it into my own name through a change of ownership.
Before proceeding, I specifically contacted Yallo and asked whether I would keep exactly the same subscription and benefits after the transfer. I was clearly told that I would, and that the only cost would be the CHF 50 ownership transfer fee. Based on this confirmation, I accepted the transfer.
What happened
One month later, after reviewing my bill, I discovered that my calls to the USA had been charged separately.
I contacted Yallo's customer service, and the agent confirmed that the benefits of my subscription were no longer the same after the ownership transfer. This was completely contrary to what I had been told before agreeing to the change.
To make matters worse, nobody was able to explain clearly why the subscription benefits had changed. The response I received was essentially: "Yes, your current subscription is different from the one you had before."
Yallo then proposed a different subscription plan, but it is still not equivalent to the plan and benefits I originally had.
Why this is unacceptable
I agreed to the ownership transfer based on Yallo's explicit confirmation that my subscription benefits would remain unchanged.
The information provided before and after the transfer was inconsistent and misleading.
Customer service was unable to provide a satisfactory explanation or solution.
Instead of restoring my previous subscription and benefits, Yallo attempted to move me to another plan.
As a long-standing customer, I expected much better. This issue is particularly frustrating because I had already experienced billing errors in the past.
At a minimum, I would expect Yallo to honor the commitment that was made to me before the transfer and restore the subscription and benefits I had originally agreed to keep.
I hope Yallo contacts me to resolve this matter fairly.
Updated - I was calling Yallo and I had a different experience today. Clear contacts, looking for solutions. So I changed my rating in more positive - from 1 star to 3 star (as it consumed me a lot of time)

SCAM Terrible experience with this operator
Terrible experience with this operator.
I received an invoice containing over CHF 100 in charges for calls to a premium-rate phone number. While I was trying to resolve the issue between Yallo and the third-party provider before making payment, Yallo added a CHF 30 penalty simply for sending me an invoice by email.
Although all my other Yallo services were fully paid, they then charged me three separate late payment fees of CHF 40 each—a total of CHF 120—based on this disputed CHF 30 fee.
I contacted the Swiss Telecommunications Ombudsman in Bern to review the case. The Ombudsman concluded that the CHF 30 fee had been introduced without proper legal notice and recommended that it be removed. Yallo appears to have accepted this point, but they still refused the Ombudsman's conciliation proposal because they insist on charging the three CHF 40 late payment fees that would never have arisen if the invalid CHF 30 fee had not been added.
This has been an extremely disappointing experience, with unreasonable fees and a refusal to resolve the matter fairly despite the Ombudsman's findings.

Worst customer service
Worst customer service ever.
After a month of no service, i initiated the transfer to a new operator. After couple of calls, they agreed quite quickly to cancel the notice period without fees, so far so good. When i say agreed, one guy wrote it somewhere on the dossier as a note. As a result, the 10 calls i had after that i had to re-explain the whole story every time, each time they got the wrong contract end date, they put all the blame on the new operator constantly. I spent my time calling Yallo blaming the new one and calling the new one blaming Yallo for not responding to their requests or confirming the wrong transfer date. It took me 6 weeks and probably 18 calls between the both of them.
And still towards the end they kept asking if we wanted a better price, an upgrade in the subscription, if we contacted their IT to ask for a new sim card even though i had request the cancellation for weeks already…after all of this i received yesterday a mail through the post telling me i got an upgrade in my subscription. Absolute joke.

Terrible experience with Customer Service
Terrible experience with Customer Service and Support. Every time you contact them, you talk with a different operator who tells you different things. It is impossible to have written confirmation of the information shared. Impossible to reach out to them via chat, so stay away.

Terrible customer service
After changing operator I had an outstanding bill that I wasn't aware of, got sent 40chf penalty that had to be paid in 24h because of unreasonably tight deadlines, post-b delivery times, weekends, and bank transfer delays. Yallo claims to have sent a soft reminder but can't even tell me if it's an SMS or an email, because probably that didn't even happen. It's all a scam to extort extra money.
Stay away from this garbage.
Edit. Yallo is telling me in the reply to this review to contact them to review this issue. I've been trying to contact them for 3 weeks and so far they have ignored me.

Very disappointing experience with Yallo.
I was sold a mobile plan over the phone and was given a good deal: 12.- unlimited data. However, I later discovered that the Dayspeed option was being charged every single day, resulting in more than CHF 20 of unexpected extra costs per month.
When I requested access to the recording of the sales call to verify exactly what had been said, Yallo confirmed that the call had been recorded but refused to provide a copy, claiming they were unable to do so.
If the same story happened to you, contact me and if we're enough we should bring this to court together 💪

I am still trying to get them to cancel a contract that I never confirmed in the first place. The only time that they call me is to sell me something further. when I tried to explain my situation she put the phone down on my. This is a SCAM company. the last time I left a review they responded to say so sorry they will sort it out, nothing! havent heard a thing. My experience with WINGO has been worlds apart! 10 x better. beware of them giving yallo any details otherwise you till start receiving invoices!!!

A shocking experience with Yallo Mobile…
A shocking experience with Yallo Mobile — if I could give zero stars, I would!
The service provided was absolutely not as advertised or promised. I signed up expecting reliable coverage, stable data speeds, and professional customer support, but the reality was the complete opposite.
The network connection is inconsistent, calls frequently drop, and the mobile data is often painfully slow or completely unusable. To make matters worse, my roaming was blocked from the very beginning, despite it being fully paid for. Trying to resolve the issue was nearly impossible because I could never get through to customer service.
Dealing with customer support was incredibly frustrating — long wait times, generic responses, rude employees, and absolutely no effort whatsoever to resolve the problems. It genuinely felt like they stopped caring the moment the contract was signed.
What makes this even more unacceptable is that the service I received did not match what was offered during signup, which feels misleading and dishonest.
I would not recommend Yallo to anyone looking for trustworthy or reliable mobile service in Switzerland. Save yourself the stress, frustration, and wasted time by choosing another provider.

I keep getting calls from them.
I keep getting calls from them with offers for worldwide roaming at ridiculously low prices. Strangely, the offer is only available over the phone and isn’t listed on their website. Personally, I find it hard to believe, and the customer service reps don’t speak the language very well—they almost seem to be making fun of you or trying to be funny.

Horrific customer service
Horrific customer service. In many years with Yallo, i’ve never had issues. But they changed their billing delays and I didn’t know about it. And when asking them to wave the late payment fee this one time, they didn’t do anything to help. Very very dissapointed with how they operate. And the customer service agent kept talking over me. Like an automated robot.

Yallo advertises plans like CHF 27.90
Yallo advertises plans like CHF 27.90, but adds a hidden activation fee (CHF 59.90) and presents invoices in a very confusing way.
The bill is filled with unnecessary numbers, as if it’s intentionally designed to be hard to understand. Prices are artificially increased and then “discounted” to make it look like a deal, instead of showing a clear and honest final amount.
On top of that, contacting customer service is not free, which makes it even harder to clarify the bill. It feels like the whole system is designed to keep customers confused rather than informed.

They made me an excellent offer for their internet at home. Would have been fantastic if it had been working. After more than a week not working and with constant contradictory messages from their assisting teams, they told me I could only cancel for a fee of 200 for a service they could not provide. They could only cancel for free if the technical team - who never came back - confirmed they could not provide this service.
By far the worst customer experience I have ever had in my entire life.

Worst experience ever.
We were already customers. We moved apartment and they sent us a modem not working. In more than 1 month they have not been able to fix the issue. We had to give up.
Worst experience ever. Don't go with them.
