A phone charm can transform a plain handset into something that looks and feels like your own, but the wrong attachment method can scratch a case, block a port or drop the charm within a day. Getting it right starts with looking at your case, not your charm: the openings, loops and edges already built into the case decide which method will actually hold.
Most phone cases fall into one of three categories: those with a dedicated hole or loop for straps, those that can be used with a compatible attachment card, and those without a suitable attachment point. Working out which type you have takes only a couple of minutes and helps you choose a secure attachment method.
The safest attachment point on a phone case is one designed for the job, so start by checking whether your case has a built-in lanyard hole or loop. If it doesn’t, a compatible attachment card may provide another option. Avoid using openings intended for buttons, cameras or other controls as attachment points.
Check for a Dedicated Lanyard Hole or Lanyard Loop
Look along the bottom corners and side edges of the case for a small reinforced hole. Some cases mould this as a loop that sits slightly proud of the case edge, which makes threading a cord through it easier. If you find one, this is the point to use first.
Check Clearance Around Buttons, Ports and the Camera
Run a finger around the case openings for the phone’s controls, charging port and the camera opening to see how much space surrounds each one. A charm cord that sits too close to any of these can rub against the button, catch on the charging cable, or nudge into the camera's field of view. Note which gaps are actually free before deciding where the charm will sit.
Match the Charm Hardware to the Attachment Point
A charm with a fine cord suits a narrow lanyard hole, while one fitted with a lobster clasp or jump ring needs a slightly wider opening or loop to close around. Forcing a clasp through a hole that's too small can crack the case at the edge, so match the hardware to the opening rather than the other way round.
Use an Existing Case Opening
If your phone case has a purpose-built lanyard hole or loop, many phone charms can be attached using a small string loop or cord, then gets pulled back through itself to tighten. Only use an opening designed as an attachment point, as threading a charm through cut-outs intended for buttons or other controls could interfere with the phone’s operation or place unnecessary strain on the case.
Thread a String Loop Through a Lanyard Hole
Take the loop end of the phone charm strap and push it through the lanyard hole from the back of the case. Once enough of the loop is through, feed the charm (or the beads and nylon cord attached to it) through that loop. Pull gently until the loop sits snug against the case edge.
Pass the Charm Through the Loop to Secure It
With the loop through the opening, pass the full charm through the loop rather than tying a knot around the case. This keeps the attachment reversible and avoids putting stress on a single point of the case material. Give it a firm tug to check it has drawn tight before letting the phone hang from it.
Options for Cases Without Attachment Holes
If your case has no built-in lanyard hole or attachment point, a compatible attachment card may be a suitable option. These are designed to sit between the phone and case, with a tab extending through the charging-port opening for the charm or strap to attach to.
Use an Attachment Card Through the Charging Port Opening
An attachment card is a slim tab designed to sit between the phone and the case, with a small loop or tab extending through the case’s charging-port opening. The charm or strap then attaches to that external loop. The card should not sit inside the phone’s charging socket, and the charging cable should still connect properly once the card is fitted.
Choose a Case With a Built-In Attachment Point
If your case doesn’t have a dedicated lanyard hole or loop, don’t use button or control openings as a substitute. A compatible attachment card designed to sit between the phone and case may provide a safer way to add a phone charm without modifying the case.
Why Altering a Case Should Be a Last Resort
Drilling or cutting into a phone case can weaken or damage it and may reduce the protection it provides. It's a method some guides mention, but it turns a reversible accessory choice into permanent damage. An attachment card or a suitable replacement case does the same job without the risk.
Secure Clasps, Straps and DIY Charms
A lobster clasp or jump ring gives a phone strap or wrist strap a stronger, more adjustable connection than a plain cord loop, provided it's fitted correctly. These small metal fittings are common on both shop-bought straps and DIY phone charm projects.
Attach a Phone Strap or Wrist Strap With a Lobster Clasp
A lobster clasp opens with a small lever and closes automatically under spring tension, which makes it simple to clip onto a case's lanyard loop or an attachment card. Check the clasp has closed fully by giving it a light tug before trusting it with the full weight of the phone. This is the same fitting used on a wrist strap, so the same check applies whether the strap loops around your hand or simply hangs from the case.
Use a Jump Ring and Pliers Carefully
A jump ring is a small split ring used to join a charm to a clasp or loop, and it needs to be opened sideways with pliers rather than pulled straight apart. Twisting it open keeps the ring's shape intact so it closes properly afterwards. Two pairs of pliers, one to hold each side, make this easier than trying to manage it with fingers alone.
Make a Simple DIY Phone Charm With Beads and Cord
A DIY phone charm can be as simple as threading beads onto a length of nylon cord and knotting both ends into a loop. Nylon cord holds a knot well and resists fraying better than cotton string, which matters given how much handling a phone charm gets. Double-knotting the ends.
Keep Your Charm Secure in Everyday Use
A charm that passes a quick check when you attach it can still work loose after a few days of normal handling, so a proper test and occasional recheck matter more than getting the initial knot right. It’s worth checking the attachment periodically, as cords, loops and clasps can loosen with everyday use.
Test the Attachment Before Carrying Your Phone
Before normal use, gently check the attachment by hand to make sure the loop, clasp or attachment card feels secure and does not shift easily. If anything moves, stretches or feels loose, tighten it or choose a different attachment method before carrying the phone.
Avoid Blocking the Charging Port or Controls
Check that the cord or clasp doesn't sit across the charging port opening, since this can stop a cable from seating properly or press against the port's contacts over time. The same applies to the mute control and volume controls; the charm should hang clear of anything you need to press or plug in daily.
Remove or Reposition a Charm if It Snags
If a charm regularly catches on a pocket, bag strap or car seatbelt, move it to a different opening or shorten the cord rather than leaving it to pull on the case edge repeatedly. Repeated snagging is one of the more common ways a lanyard hole eventually splits, so it's worth adjusting early rather than waiting for it to fail.
Find the Attachment That Works for Your Case
Many phone cases provide a suitable way to attach a phone charm, while others may require a compatible attachment card or accessory. First check whether your case has a dedicated lanyard or attachment point. If it doesn’t, consider a compatible attachment card rather than using an opening intended for the phone’s buttons or controls. Checking clearance around the buttons, camera and charging port before you attach anything is what keeps the charm secure and the phone fully usable.
A charm is one of the simplest ways to bring some personal style to an otherwise identical phone case, and getting the attachment right means it stays that way rather than becoming a loose cord you keep re-tying.

If you plan to add a phone charm, check the case design and choose a compatible attachment method before fitting one.
Frequently Asked Questions
How do I attach a phone charm without a hole in my case?
A compatible attachment card is one common option. It sits between the phone and case, with its tab extending through the case’s charging-port opening so the charm can attach externally. Always check that the case still fits properly and that the charging cable connects normally.
Where should a phone charm go on an iPhone case?
The best position depends on the case design. Use a built-in lanyard hole or dedicated attachment point if the case has one. If not, a compatible attachment card may be an alternative. Keep the charm clear of the camera, buttons and charging connection.
Can I attach a phone charm through the charging port opening?
Yes, if you use a compatible attachment card designed to sit between the phone and case, with its tab extending through the case’s charging-port opening. The card should not go inside the phone’s charging socket, and the charging cable should still connect securely.
How do I attach a phone charm with a lobster clasp?
Open the clasp's small lever, hook it onto the case's lanyard loop or an attachment card, then release the lever so it closes under its own spring tension. Give the clasp a light tug afterwards to confirm it has closed fully before trusting it with the phone's weight.
Will a phone charm interfere with charging?
A well-fitted attachment card or cord sitting beside the charging port shouldn't stop a cable from connecting, though a bulky clasp or thick cord positioned directly over the port can. It's worth plugging the phone in once the charm is attached to confirm the connection is still solid.
