Pros and cons
Lyca Mobile Ireland
Pros
- Unlimited Plus is priced at €10, which ranks 22 of 173 and sits well under the €23.19 typical unlimited price
- Billing is prepaid and rolling, so there is no credit check and no long lock in before you use the line
- The contract length on file is 1 month, so a bad month costs a month rather than a year
Cons
- Entry price of €9 ranks only 155 of 258, so the headline figure is not the cheapest on the table
- Support runs on help centre only, which is thin help for anyone whose prepaid account needs more than a self service lookup
- The offer score of 8.8 trails the cost score of 9.3, so the value is in the price rather than in the extras
T-Mobile Polska
Pros
- Two billing styles in one place: contract and prepaid covers both a prepaid card and a contract SIM, so a short month and a longer plan come from the same seller type of network.
- Unlimited data is priced at PLN 75 on the Abonament komorkowy plan, which also ranks 59 of 173 brands on that measure.
- Sim only is available, so you can bring your own handset and pay only for the network side.
Cons
- The contract plan runs 24 months, so the unlimited price is tied to a long commitment rather than a rolling monthly deal.
- EU roaming is on fair use terms, which is weaker than plans that include roaming in the monthly price.
- The range runs in Poland, so the plan, support and the prepaid card are aimed at Poland only.
Who each suits
Lyca Mobile Ireland
Who it suits
- Someone in IE who wants a low cost data line with no handset to pay off
- A heavy data user who values unlimited data at €10 over per gigabyte allowances
- Anyone switching from a contract SIM who wants rolling prepaid billing on 1 month
Who should look elsewhere
- You want a bundled new phone, since these plans are sim only with no device
- You need a fixed end date in writing, since billing is prepaid and rolling rather than a contract, which GETESA offers on prepaid and contract
- You want a first line that carries a brand new network in Ireland, since these plans ride on the Three network
T-Mobile Polska
Who it suits
- People living in Poland who want a plan sold by the network itself rather than a reseller, given network and PL.
- Shoppers who want both a prepaid card and a contract option on the same account, since contract and prepaid lists both.
- Households wanting a multi line discount, or travellers who want eSIM and Wi-Fi calling included.
Who should look elsewhere
- Anyone outside PL, where the prepaid card and contract plans do not reach.
- People who want EU roaming included in the monthly price, since fair use applies.
- Readers who need a short rolling commitment, because the contract option runs 24 months.

Questions about each
Lyca Mobile Ireland
How much does Lyca Mobile Ireland cost at entry?+
Entry pricing starts at €9, and billing is prepaid and rolling, so the figure is prepaid rather than tied to a minimum term. Because the contract length on file is 1 month, the same rate covers each cycle. There is no separate introductory price that rises later.
What does unlimited data cost on Lyca Mobile Ireland?+
Unlimited Plus is €10, which puts Lyca Mobile Ireland 22 of 173 on unlimited pricing. Set against the typical unlimited price of €23.19 across the plans we track, the figure here sits well under the middle of the field. It is the strongest reason to shortlist this brand.
T-Mobile Polska
How much does a T-Mobile Polska plan cost at the cheapest end?+
Plans start at PLN 30 per month on the prepaid card. The reference tariffs add GO! S and GO! M, a smaller and a larger data bundle billed monthly on a short cycle, so entry pricing stays flexible rather than locked. Unlimited data sits higher, at PLN 75 on the Abonament komorkowy plan.
What does unlimited data cost, and how long am I tied in?+
The Abonament komorkowy plan carries unlimited data at PLN 75 per month and runs 24 months. That is the trade-off to weigh: a lower entry price on the prepaid card tariffs, or unlimited data on a long contract. On that measure the brand ranks 59 of 173.
