Olimit Tips & Tricks
Are 30-day SIM Only plans really the best value?
30-day SIM Only deals offer great flexibility and no long-term commitment, making them ideal if you want to stay in control or avoid credit checks. However, longer contracts such as 12, 18, 24 months sometimes come with better discounts, extras, or faster network access. If you’re after freedom and short-term savings, 30-day plans are a solid choice — just make sure the data, minutes, and roaming fit your needs.
Who should choose a 30-day SIM Only deal?
A 30-day SIM Only plan is perfect for people who want flexibility without commitment. It’s ideal if you’re between contracts, trying out a new network, visiting the UK, or if you’ve been declined for a contract. These plans usually don’t require a credit check and let you cancel or switch anytime — making them a smart choice for short-term or low-risk mobile use.
