Looking for some advice on mobile phone providers. My UK contract is about to expire so have been looking for a new Finnish sim card. I did a bit of shopping around and settled on Telia for a basic monthly contract including calls and mobile data.
I applied for the contract and just received a letter requesting an advance payment for the subscription of 340€. I guess because I've been in Finland only a year, my Finnish credit history doesn't yet exist, so I guess they're not too keen on giving me a subscription contract upfront without some sort of security deposit – which seems fair to me

It's just surprising that it's so much! The monthly charges are only 24€, which would mean a deposit of 13 months. Given that the contract doesn't have a fixed term and can cancel any time, it seems like an unreasonable amount to charge upfront. They mention it's a credit to my account, which in theory would be refunded if I cancel early, but the negative reviews online from previous customers, and limited information in English doesn't fill me with confidence.
Was wondering if anyone had any alternative recommendations on a provider that wouldn't require such a large advance deposit?
Thanks in advance
