Pros and cons

Pros

  • maXXim is a Sim only provider as well as a full flat rate seller, so a data only line and a phone plan come from the same seller.
  • 5G is yes on the Allnet Flat range, and an Esim is available for a new number.
  • included spans 33 countries, so trips inside the EU do not need a separate roaming plan.
  • Contract terms run 1 and 24, so a short monthly option sits alongside the longer commitment.
  • Support reaches you on email, phone and help centre, covering phone and email as well as a help centre.

Cons

  • The 1 and 24 range is the catch on the €4.99 entry price, since the cheapest headline rate ties to the longer term.
  • Only contract and rolling billing appear in contract and rolling, with no prepaid option in the list.
  • DE covers a single market, so the flats are written for a German address rather than a multi market account.
  • Broadband is priced apart from the line, with a setup fee of €49.99 on a connection reaching 1,000 Mbps.

Scored 9.1 / 10 by TariffCue.

Who it suits

  • Households in Germany that want a single flat rate with data rather than a capped minutes and texts bundle.
  • Travellers who regularly cross borders inside the EU and prefer roaming handled inside the plan.
  • People who want a German provider with a named legal entity and a choice of support channels.

Who should look elsewhere

  • Shoppers outside Germany, since DE lists a single market and the flats are sold on that base.
  • Buyers who want prepaid billing, since contract and rolling covers contract and rolling terms only.
  • Households expecting a single bill for mobile and fibre, since the connection adds a setup fee of €49.99.

Core features

The mobile side of maXXim covers a Sim only line and the Allnet Flat range, so a data only number and a phone plan come from the same seller. Sim only is offered, and 5G is yes on the Allnet Flat plans. An Esim is available, which suits anyone who wants a new number without waiting for a card to arrive. Data is what these plans are built around: the Allnet Flat tiers differ mainly in volume, with the smallest allowance at the bottom of the range and a far larger one at the top. Roaming is the other part of the package, with EU roaming included and coverage across 33 countries. Contract length is a choice rather than a fixed rule, since plan terms run 1 and 24. On the fixed line side, maXXim runs fibre technology on fttc and fttp, with top download speed of 1,000 Mbps, upload of 5.8 to 40 Mbps, a router from FRITZ!Box 7510, 7630 or 7690, and a setup fee of €49.99. Broadband pricing follows the rule of a Permanent flat rate with no hidden price jumps.

The company behind it

maXXim is operated by Drillisch Online GmbH, with its headquarters in Germany. That matters for a broadband customer as much as a mobile one, because the legal entity named in the imprint is the party the contract is held with. Support runs on email, phone and help centre, which means email, phone and a help centre are all listed routes to the same company rather than an outsourced third party desk. For a market that is a single country, DE, having the legal entity and the support team in the same place tends to make contact simpler.

How maXXim compares

Frequently asked questions

What does the cheapest maXXim flat rate cost per month?+

The Allnet Flat range opens at €4.99 per month, and that entry plan carries the smallest data volume of the set. Higher tiers add more data at a higher monthly fee, so the headline price alone does not show how much allowance you get. The €4.99 figure is the entry point for the range, rather than every plan in it.

Does roaming cost extra on maXXim plans?+

EU roaming is included on the Allnet Flat range, covering 33 countries. That means trips inside the EU are handled inside the plan instead of through a separate roaming add-on, though the listing covers the Allnet Flats rather than every line a customer holds.

How long is the contract on a maXXim plan?+

Plan terms run 1 and 24, so there is both a short monthly option and a longer commitment. The Allnet Flat plans are published at the longer term, which is the trade-off behind the low entry price of €4.99.

Can I get a maXXim plan as an eSIM?+

An Esim is available, so a new number can be set up digitally, and the range is sold for DE. That fits anyone changing device or adding a second line without waiting for a physical card to arrive, and 5G is yes on the same plans.

Who am I buying the maXXim service from?+

The listed market is DE, and the legal entity behind the service is Drillisch Online GmbH with its headquarters in Germany. Buying from a provider that names its own imprint entity means the contract party is the same company behind the network service.

How do I reach maXXim support?+

Support runs on email, phone and help centre, covering email, phone and a help centre. Phone support matters most for broadband faults, while the help centre handles plan detail and contract questions across the contract and rolling terms listed for the range.

Can I get maXXim broadband as well as mobile?+

The range covers both. The fixed line side runs on fttc and fttp with a top download of 1,000 Mbps and upload of 5.8 to 40 Mbps, a router from FRITZ!Box 7510, 7630 or 7690, and a setup fee of €49.99 on connection.

Will my broadband price rise later?+

Broadband pricing follows a Permanent flat rate with no hidden price jumps. For a household taking mobile and fibre from the same provider, that stated rule is worth reading alongside the €4.99 entry price on the mobile side before signing a longer term.
